The Alpha Photo Engraving is a set of cards from 1894. There is only 1 known copy of each card, and several cards that are speculated to have been produced, but have not been found. Dan McKee currently owns every known card from this set. The set is very significant to many collectors, as it has the earliest known cards of McGraw, Jennings, Joe Kelly, and potentially Keeler if it is ever found. Also has other HOFers such as Robinson, Hanlon, and Brothers.
