"Doppelkopf" , saxon pattern , Piatnik , 24c.
[ The ace of acorns on the deck bears the legend " Sehr feine schwerdter deutsche"- "extra fine sword-german ", a refrence to the swords found on the single faced version's ace of acorns]
The following deck is the 24-card version of a saxon pattern ( which normaly comes in 32 card decks), for playing the game of doppelkopf (but the game in question actualy needs 2 such decks of cards shuffled together- go figure)
For another version of the deck, see : http://anthonylesq.blogspot.com/2011/10/saxony-pattern-cards-single-vs-double.html
Note the ace of hearts . In the middle of the card, there is a blank circle. I suspect this was where the tax stamp was supposed to go.
