So many beautiful decks!
I have only one to show off, but it's a real beauty. And I know very little about it. It was given to me by an old roommate. That was around 1990 and the cards were already old-looking then (though only the box shows much wear). I assume it's Ukrainian, like my roommate, based on the writing on the box. But it could be Russian or something else; I can't read what it says.
I looked on the Playing Card Museum website and didn't find one like it, though I could have missed it -- there are so many decks there and the thumbnails are so small.
Here are some pics. First one shows the back, joker, and an ace. Then the court cards, which I find very beautiful. Then two of the box, front and back. The picture on the front of the box has an out-of-focus candle, which I like to think suggests cartomancy
And it wasn't till I photographed it today that I noticed the cards in the picture are from a different deck!
