Santa Claus

The most beautiful Santa postcard was this card, sent by Laura, from USA (FB-swap).
(Received in June, 2012)

Santa Claus, also known as Saint Nicholas, Father Christmas and simply "Santa", is a figure with legendary, mythical, historical and folkloric origins who, in many western cultures, is said to bring gifts to the homes of the good children during the late evening and overnight hours of Christmas Eve, December 24. 

Saint Nicholas of Myra is the primary inspiration for the Christian figure of Sinterklaas. He was a 4th century Greek Christian bishop of Myra (now Demre) in Lycia, a province of the Byzantine Anatolia, now in Turkey. Nicholas was famous for his generous gifts to the poor, in particular presenting the three impoverished daughters of a pious Christian with dowries so that they would not have to become prostitutes. He was very religious from an early age and devoted his life entirely to Christianity. In continental Europe (more precisely the Netherlands, Belgium, Austria and Germany) he is usually portrayed as a bearded bishop in canonical robes. In 1087, the Italian city of Bari, wanting to enter the profitable pilgrimage industry of the times, mounted an expedition to locate the tomb of the Christian Saint and procure his remains. The reliquary of St. Nicholas was desecrated by Italian sailors and the spoils, including his relics, taken to Bari where they are kept to this day. A basilica was constructed the same year to store the loot and the area became a pilgrimage site for the devout, thus justifying the economic cost of the expedition. Saint Nicholas was later claimed as a patron saint of many diverse groups, from archers, sailors, and children to pawnbrokers. He is also the patron saint of both Amsterdam and Moscow.

Virginia

It's also from Laura (USA), through FB-swap.

Virginia, officially the Commonwealth of Virginia, is a U.S. state located in the South Atlantic region of the United States. Virginia is nicknamed the "Old Dominion" and sometimes the "Mother of Presidents" after the eight U.S. presidents born there. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city and Fairfax County the most populous political subdivision. The Commonwealth's population is over eight million.

Mount St. Helens

Laura's next postcard from USA (FB-swap).
(Received in June, 2012)

Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles (154 km) south of Seattle, Washington and 50 miles (80 km) northeast of Portland, Oregon. Mount St. Helens takes its English name from the British diplomat Lord St Helens, a friend of explorer George Vancouver who made a survey of the area in the late 18th century. The volcano is located in the Cascade Range and is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire that includes over 160 active volcanoes. This volcano is well known for its ash explosions and pyroclastic flows.
Mount St. Helens is most notorious for its catastrophic eruption on May 18, 1980, at 8:32 am PDT, the deadliest and most economically destructive volcanic event in the history of the United States. Fifty-seven people were killed; 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche triggered by an earthquake measuring 5.1 on the Richter scale, caused an eruption, reducing the elevation of the mountain's summit from 9,677 ft (2,950 m) to 8,365 ft (2,550 m) and replacing it with a 1 mile (1.6 km) wide horseshoe-shaped crater.[3] The debris avalanche was up to 0.7 cubic miles (2.9 km3) in volume. The Mount St. Helens National Volcanic Monument was created to preserve the volcano and allow for its aftermath to be scientifically studied.
As with most other volcanoes in the Cascade Range, Mount St. Helens is a large eruptive cone consisting of lava rock interlayered with ash, pumice, and other deposits. The mountain includes layers of basalt and andesite through which several domes of dacite lava have erupted. The largest of the dacite domes formed the previous summit, and off its northern flank sat the smaller Goat Rocks dome. Both were destroyed in the 1980 eruption.

Mount Hood, Oregon

This card is also from Laura,  USA, from FB-swap.
(Received in June, 2012)

Mount Hood, called Wy'east by the Multnomah tribe, is a stratovolcano in the Cascade Volcanic Arc of northern Oregon. It was formed by a subduction zone and rests in the Pacific Northwest region of the United States. It is located about 50 miles (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties. In addition to being Oregon's highest mountain, it is one of the loftiest mountains in the nation based on its prominence.
The height assigned to Mount Hood's snow-covered peak has varied over its history. Modern sources point to three different heights: 11,249 feet (3,429 m) based on the 1991 U.S. National Geodetic Survey, 11,240 feet (3,426 m) based on a 1993 scientific expedition, and 11,239 feet (3,426 m) of slightly older origin. The peak is home to twelve glaciers. It is the highest point in Oregon and the fourth-highest in the Cascade Range. Mount Hood is considered the Oregon volcano most likely to erupt, though based on its history, an explosive eruption is unlikely. Still, the odds of an eruption in the next 30 years are estimated at between 3 and 7 percent, so the USGS characterizes it as "potentially active", but the mountain is informally considered dormant.

Washington DC

These two postcards were sent by Laura, a postcard-collector from the USA (originally from Germany), I got them through FB-swap.

Washington, D.C., formally the District of Columbia and commonly referred to as Washington, "the District", or simply D.C., is the capital of the United States. On July 16, 1790, the United States Congress approved the creation of a capital district as permitted by the U.S. Constitution. The District is therefore not a part of any U.S. state.

The states of Maryland and Virginia donated land along the Potomac River to form the federal district; however, Congress returned the Virginia portion in 1846. The City of Washington, located east of the preexisting port of Georgetown, was founded in 1791 to serve as the new national capital. Congress consolidated the whole District under a single municipal government in 1871. The city and the U.S. state of Washington, which is located on the country's Pacific coast, were both named in honor of George Washington.

Orchid

This beautiful flower-postcard is from Poland, sent by Marta (FB-swap).

Orchidaceae - Orchid
The name comes from the Greek ὄρχις, literally meaning "testicle", because of the shape of the root. Linnaeus categorized the family as Orchidaceae. Orchid was introduced in 1845 by John Lindley in School Botany, due to an incorrect attempt to extract the Latin stem (orchis) from Orchidaceae.
The Greek myth of Orchis explains the origin of the plants. Orchis, the son of a nymph and a satyr, came upon a festival of Dionysios (Bacchus) in the forest. He drank too much, and attempted to rape a priestess of Dionysios. For his insult, he was torn apart by the Bacchanalians. His father prayed for him to be restored, but the gods instead changed him into a flower.
These flowers were previously called Orchis, Satyrion (Satyrion feminina), or "ballockwort".
