One more Gehrig Type I - looking for input.

[GehrigFan]

Since I had my other Gehrig question answered so fast, let me throw out a tougher question. The image below is of a Gehrig I just bought from an Auction House. They described it as a Yankees Picture Pack photo. It is blank on the back, measures about 4x6," is a crystal clear image, and came in an envelope with Lou Gehrig typed on the front. It also came with a similar picture of Frank Crosetti, also with the same envelope and his name on it.

Has anyone ever heard about a Yankees Picture Pack from the 1930's before? I 'm too lazy to look it up right now, but I believe they played together from about 1932-1939. I'm quite sure it is a Type I, and while the team *might* issue a Gehrig photo after his career as a souvenir, it doesn't make sense that they would issue a Frank Crosetti later on. He wasn't exactly a huge name.

So what do you think - remnants of a Yankees Picture Pack from the 1930's, or just original snapshots that a fan put in envelopes and typed their names on?
