2 t206 proofs of same card?

[Jobu]

These are definitely different cards - check the right edge at the top and the crop on the bottom right of one but not the other. Also, unless the scan is off, one is missing the peach layer.

There are some T206 proofs with multiple copies known, some are type 1 and type 2 where there was a design change while others have multiples of the same card. Some have the name missing as well. The Resource has a gallery that has some of them:

I think the story is that all of these walked into a show on the 70s or 80s, including an Eddie Collins with bat and a few (?) Southern Leaguers that were never actually printed for some reason (I think Olbermann owns those).

As for the multiple cards, these could have been printed with multiples on single sheets as they were later in the production or they could have been printed in a different way, without a lot of multiples. There is a Wagner proof strip that was found in one of Honus Wagner's uniform pants pockets in his attic:

This is a 5-card strip, though obvious doesn't tell us how big the full sheet was or how it was laid out.
