I listed a few Russian slot cards on eBay a few days ago and then today I listed well over 100 different Russian casino slot cards on my Delcampe store. Here's a link that will just show all the Russian cards currently listed there, about 140+ cards now. Note that I can deal direct, you do not need a Delampe account. And if buying multiple cards I can reduce prices somewhat or make me an offer on any cards of interest.
