bcornellAnother possibility is that the cards were issued in series (2 or 3?) rather than all at once and one of these series was short-printed. This is definitely the case with T222 Fatimas, which came out the following year: there are 36 players that are at least 5-10x easier to find than the other 16.
On a related Fatima note, I've always wondered why the 1914 single player cards are so much scarcer than the 1913 team cards. With other multi-year issuers in the same era (Obak, Cracker Jack, and others), the first year cards are always much tougher, but it's the opposite with the Fatima sets.
