I'm trying to figure out what I have. Sam Moffet of the 1887-88 Indianapolis Hoosiers in a batting pose. It's 2.75 x 3.5 and is some kind of photo process on glass with which I am not familiar. There's a depth to it - as if some parts are in front and some in back. Rough edges and it's a bit thicker than 1/8th of an inch.
I can't find anything to compare against so I have no clue about this piece. Any ideas?
