A couple hugs while standing near a Christmas tree made out of plastic bins and plastic hampers outside the Museum of History in Monterrey, Mexico, December 4, 2015. The humble Christmas tree has a rich history, from evergreen trees used to symbolise eternal life in Ancient Egypt to tree worship among pagan Europeans. The modern version has its origins in Germany, where the song “O Tannenbaum” is still a festive favourite. Today the traditional tree with lights and decorations appears in cities including Washington, Moscow and Beirut. Alternative constructions range from recycled rubbish in Mexico City to old window frames in Rakvere, Estonia. Whatever the shape or size, the message is the same: Merry Christmas.

Number 10. BELL H-13 SIOUX was a two-bladed, single engine, light helicopter built by Bell Helicopter. Westland Aircraft manufactured the Sioux under license for the British military as the Sioux AH.1 and HT. In 1947, the United States Air Force ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux. The Bell-built H-13 B is seen airborne in this April 29, 1951 photo. The helicopter is equipped with a 173 horsepower engine, cruises at 85 miles per hour, climbs 900 feet in a minute and has a service ceiling of 11,500 feet. (Photo by AP Photo)

“The Trabant is a car that was produced by former East German auto maker VEB Sachsenring Automobilwerke Zwickau in Zwickau, Sachsen. It was the most common vehicle in East Germany, and was also exported to countries both inside and outside the communist bloc. The main selling points was that it had room for four adults and luggage in a compact, light and durable shell and that it was fast (when introduced) and durable. With its mediocre performance, smoky two-stroke engine, and production shortages, the Trabant is often cited as an example of the disadvantages of centralized planning; on the other hand, it is regarded with derisive affection as a symbol of the failed former East Germany and of the fall of communism (in former West Germany, as many East Germans streamed into West Berlin and West Germany in their Trabants after the opening of the Berlin Wall in 1989). It was in production without any significant changes for nearly 30 years with 3,096,099 Trabants produced in total”. – Wikipedia

The Trabant, also known as the Trabi, was among the main cars produced in communist East Germany and built by VEB Sachsenring Automobilwerke in Zwickau for 30 years until 1989. Today the car has cult status for many followers and one company, IndiKar, is even seeking to revive the brand in a modern, electric version. (Photo by Carsten Koall/Getty Images)
