The Soviet Union operated pretty much in isolation from the rest of the world from 1922 to 1991. They had their own nuclear weapons buildup and their own space program, plus manufacturing and technological advances like every other nation, but we didn't get to see them. When they were revealed later, the photographs of Soviet machinery, vehicles, and architecture seemed to come from some bizarro world where nothing is familiar to us. Take, for example, the snowmobile pictured above from the 1950s. It was the Sever-2 Aerosan, developed for the military, seemingly by plopping a sedan body on top of skis and powering it with an airplane engine. You can see a gallery of things made in the USSR, ranging from goofy car designs to scary military installations to Tetris, at Messy Nessy Chic.
