Recently rediscovered in my boxes of junk, I purchased these while in the Czech Republic a few years ago, where Angela and I wandered into an antique shop in the "Art Nouveau" district of Prague. Full of the typical antiques and curiosities, it was also full of boxes and boxes of old Soviet era trade union pins being sold for cents apiece. It was hard to find repeats in the thousands of pins, and each design was unique and beautiful, sometimes identifiable to the trade but most mysterious acronyms or illegible (to me) czech.
