Vintage Piedmont Baseball Cards?
 

For sale on Offerup, they seem to have some signs of age but I am far from a expert. Was curious if anyone has any insight on if these are reproductions or the real deal. Hoping the knowledge of the forum can help out on this one. Thanks

I don't like the backs to be honest. Those dark solid lines shouldn't be dark solid lines, they should be two really thin lines next to a slightly wider line. A lot of reprints/counterfeits are printed on modern printers that can't print the thin lines so they come out as a thick solid line like the ones in your pics. Just my 2 cents.

You’d have more luck in the prewar forum than this postwar one.
