Antique 1928 20s Congress 606 Playing Cards Deck Bridge

Box and cards seem to be in "good " condition cards needing cleaning. I counted 52 cards. I've been informed by a collector that there is a date code of "K" on the ace of spades and that means the deck is from 1928. Note that I am not a professional playing card grader. We take returns within 30 days if not satisfied.
