The newer reprints are different on the back. I looked for a bit and could not find another reprint release having the same backs. But even in the pictures posted here, the backs look different besides the white. Where the card number in the baseball appears to be positioned differently.
Aside from the reprint sets themselves, apparently uncut sheets also had existed for these. Perhaps this other card came from a sheet?
