The deck was printed by the Obchodni Tiskárny Kolin N.P. (OTK) from Prague. Their logo is on the Ace of Hearts. The deck published by the Čedok - Interhotel combination in 1975. We have had the blue backed deck in our collection for many years now, but only very recently we acquired a deck with a red back design and found that all the images on the courts were different. Both our decks came without a box. Although they were probably published as a double deck, we've never seen an original presentation box for them.
The decks were clearly designed by the same artist/illustrator. Each deck consists of 52 cards and 2 identical jokers.
