“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)

Professional conceptual category winner. Greetings from Mars, by Julien Mauve, France. Mauve says: “I have always wondered what it would be like to discover a totally different world ... and to photograph it for the first time as if I was Ansel Adams. So I came up with this project, which is about space exploration and discovery. But it’s also about our behavior in front of landscapes and how we create pictures that will share our personal story with the world”. (Photo by Julien Mauve)
