Original Baseball Oil Paintings. Both roughly 20x26.
The first is based off of the famous photo of Ty Cobb sliding into third base during the 1909 World Series while Honus Wagner tags him out. The painter, an otherwise unidentified Mr. or Ms. J. Cox, chose to add a "5" to Cobb's back, though it would be nearly two decades before players would begin wearing numbers on the backs of their uniforms.
The second is a little harder to peg. The background looks an awful lot like the short porch of the Polo Grounds curving into 258 feet in right field. The player looks to be receiving a throw from the outfield, but doesn't seem to be wearing catcher's gear (either way, he's got an infielder's mitt on. Anyone who has any more information on these paintings would be much appreciated. I've tried with no luck to find the artist for a few years now. Found in a North Carolina Goodwill for $20 a piece.
