Yesterday we had the postcards from a Soviet city too. It was city Sevastopol you can see that posting here. Now we have another card set, coming from Odessa town. It is now in Ukraine, but in 1989 it was still part of the Soviets and those postcards from that time.
In the University of California, Santa Cruz, there is a large collection of photos (about 10 thousand!) of the Soviet Union, taken by photographer Branson DeCou who travelled around the country a lot. At that time they were able to take color photos but for some reason the photographer preferred to take black-and-white ones and then colour them by himself. Taking into account the fact that it took him several hours to color just one slide, how much time then did it take him to color the whole collection?
