White on Black Double-sided, Hand-painted Scorekeeping Numbers - A Pair

I'm not entirely sure what game these were made to score, but I'm pretty certain scorekeeping that was their original purpose--perhaps they tracked balls and strikes? In any case, I think the hand-painted numbers are about as good as they could be, and perfect in this very painterly white against black. And how great this 1 and 11--I assume meant to represent 1 and 2, though, as they flag in the opposite direction, perhaps I am wrong and they stand for something else entirely?! I  think they're really beautiful.

7 1/16" t x 4 5/8" each and looks like steel to me, with holes at the top for hanging. Sold as a pair.
