Here's another one picked up at the same auction. If anyone can read lower case Russian and tell me the destination, I'd be grateful.
It's a registered philatelic cover from Odessa, Ukraine, posted 11.10.1918 addressed to somewhere I can't read. Stamps on cover are Russia currency stamps SG174, 175 and 176 (1, 2 and 3k) and Ukraine stamps SG9 (40k), L127 (3k imperf), L168 (3k perf.), and L187 (10k on 7k).
I've also included a detail of the front of the registration label for those who like that sort of thing.
