No idea where to put this so I guess it goes in this thread. I just finished reading Magnetic Mountain by Stephen Kotkin, a book about the creating of the city of Magnitogorsk in the Soviet Union in the 1930's. They basically built the city from scratch to build a steel mill and mining operation as part of early Soviet hyperindustrialization, and the book is about how the average person lived and participated in that society. If you're into this kind of reading, I highly recommend it.
Unfortunately that's the extent of the wrestling references, and all the notes lead to Soviet newspapers of the time which I certainly can't access or read.
So that's tremendously interesting to me - in the mid-1930's, there was a French wrestling troupe experienced and connected enough to travel the USSR and be sent to an extremely remote city (though nationally important), and draw packed houses. And of course it speaks to the somehow universal appeal of pro wrestling, when in contexts as varied as then and now it can still be popular.
