Jackie Robinson Question

[SetBuilder]

The term is philatelic cover. See this wikipedia page for more details about what Steve just explained.

Maybe it was just an opportunistic find in a large lot of stamp covers, where the forger chose to add the signature to "complete" the piece.

I just had a quick look, and can't find any important event involving Robinson for either date.

Most covers like this were done primarily for the novelty. Presidents names are pretty common, as most of their last names are easy to find a town for, and most also have fairly common first names.

I could see a "Jack + Robinson " cover as being something the person making it intended to get signed, but that would be unusual.

I can't say much about the autograph, I just don't know enough about it. I will say that after a brief look at pictures on the web it doesn't look good. But I'd put the reliability of my opinion on the signature as being a coin toss.

It could be that it's fake and added after, or a fake intended as decoration on a fun cover, (Back then people often didn't consider what it would seem like years later) Maybe clubhouse or secretarial? The addressee is in Maine, so she probably did it through the mail. I can see her mailing it to the team for the final touch.
