Anyone know what these cards are?

You'd have to check them to be sure of age. Not saying they are vintage, only that to be definitive you need to see them.

Assuming they pass the age tests, I don't think they are cards--those simply did not exist--but they could be cutouts from a broadside. I've found them sporadically from 1930s posters for boxers like Joe Louis. Here is an example:

Nothing like having them in hand, of course, but I'd bet my house these are fakes. Like most such attempts, there's a uniform yellowing/browning that comes from the baking or chemicals or whatever they do to try to make them look old that just doesn't capture the look of real old photos. It's an attempt at a sepia look, when in fact very few actual old photos have a sepia tone. I've seen many of these negro league team fakes over the years on eBay and elsewhere, but curiously when I tried to find a picture of one on Google I was unsuccessful.

I'm with Adam on this one.

If they were 'aged' recently, the ager did a much better job than do most.

But that opinion is based on the scans - minimally I'd need to see hi-res scans of the roughed-up edges.

Fakes today, fakes yesterday, fakes tomorrow.

From the scans they look like they were cut from a book and pasted on the cardboard. You can see them wrinkle a bit in the borders, as paper would.

Heres a close up....

Oh, I agree they are cut from something but before I pass judgment on what I'd need to see them and put them under magnification and possibly a uv light.
