Uncut Proof sheet c. 1913 with Cobb and Joe Jackson in May '24 Hunt Auctions

[packs]

I still think the biggest issue with this piece is whether or not these were baseball cards in the first place. As suggested, I think the idea that these were cards contributed to the perceived value of it. But what if these weren't cards at all? What makes them cards in their present state?

For example, I find it problematic that these baseball cards don't have team identifiers on them. Pretty unusual for a baseball card of the time, isn't it? Can anyone think of another contemporary set that didn't include team names?

Even the low-fi candy sets like Baseball Bats included team names with the images.
