For a book project on the history of trade across the early Soviet borders, I am trying to trace the paths of some key commodities.
Furs and pelts (Siberian mink, Altai squirrel, karakul sheep, etc.) were a mainstay of both official and contraband trade. They flowed out across much of the Soviet frontier, from Finland to the Far East. They were dressed, sold, and resold in Leipzig, London, and New York.
