This is a wood puzzle with a lithograph picture of a racing harness horse and driver. I found a similar lithograph by the same artist, J. Cameron, which dated from 1873. It measures 13.5 inches by 8.5 inches and has about 400 puzzle pieces. All present and accounted for. it will be dismantled and the pieces sent in a little cardboard box it came in. I doubt it’s original to the puzzle.
