These are the 1ST playing cards V3 by Chris Ramsay.
This is what Chris Ramsay states about this deck:
"Premium, crushed Bicycle stock. The V3 have the highest attention to quality of any playing cards currently on the market. Printed by the United States Playing Card Company, they feature beautiful Metalux foiling on the backs and some faces of the cards. The Deck comes in Mnemonica stack with a duplicate 4 of Spades and a playing card reveal on the King of Hearts. Both jokers are also foil stamped and identical. One ad card features the foil stamped snake designed by renowned artist Abraham Garcia Sanchez. The tuck case printed by Clove Street Press, features a mat white cardboard stock with embossing on the leaves and is beautifully wrapped with the iconic 1ST logo. The inside also features a repeated 1ST logo in gold foil. One of the nicest, and smoothest decks you will ever handle. Available now while quantities last. These will never be reprinted."
