This is a hand-painted pack that is supposed to have been made in a prisoner-of-war camp in or after WWI, but it might also be from WWII.
The painter seems to have had packs made by Piatnik, Vienna, in his mind: You can see Piatnik's horse rider logo on the Ace of Hearts, and there is 'IN' and 'W' (for 'IN WIEN', in Vienna) on the flags of the Jacks. Note the strange arrangement of index signs on the court cards.
I regret that the pack is incomplete, the King of Spades is missing. That is why I show the Ace of Hearts in this place.
