Two very different decks facing off here.
Both have vintage backs, but that where similarities end.
Gold Seal NFBs. Air cushion finish. Bicycle stock. Historic Ace of Spades. Available in black and inverse black (white). Excellent gaffs, including the "zero of hearts", usable in romantic tricks well-suited for girlfriends and Valentine's Day. A stunning and beautiful update to a classic design.
Erdnase 216s. A wholly unique finish and stock designed by William Kalush himself. Back design, believed to be over 100 years old, possibly the model from which the M.D. Smith drawings in "The Expert at the Card Table" were derived. Reproduction faces typical of pre-WWI deck design.
May the best deck win.
