Pinochle deck made by United States Playing Card Co. c.1914, its Picket 515 brand.
The deck has 64 cards, instead of the more common 48, and includes 7s and 8s, in addition to the usual 9-King and Ace in each suit. Thus, the deck has 2 x 32 cards (2 x 7-King and Ace in each suit). The cards are wide, measuring 88mm x 62mm. There is no box.
The cards are in very good, lightly used condition, with edge wear and soiling, but without other issues, except that an Ace of Clubs has a slight crease one of the corners (separately pictured).
