I am so happy that you and others are getting to photograph the wonderful sample cards at the Museum of Glass and Jewelry. I was not able to do so when I visited the museum in 1987. Although I had received permission from the government authorities to photograph sample cards, the letter did not reach my home until I was already in Europe. Of course, the director of the museum had not been sent a copy. So I had to content myself taking copious notes and mental images. Ah, the good old Soviet days!
