I found these pins at a local thrift shop, paying 50 cents for the bag. These were commemorative pins for the 1989 Perestroika traveling exhibition. I found an online article from the December 13, 1989 issue of the Orlando Sentinel announcing the exhibition's arrival, "Perestroika Comes To Orlando Show To Give Orlando A View Of Soviet Life." The pins seem to have some value, selling for several dollars each. Of course, I got them because I liked them. Plus, they reminded me of my 28mm Soviets.
