Letterhead from Harwood, 1860's. They were supposedly the first commercial manufacturer of baseballs, and the first to manufacture the modern style ball instead of the lemon peel balls.
I had 2 partials like this and one full sheet, almost legal size paper. I kept the complete one. Surprisingly I didn't get much for the other two, enough that mine ended up being free, but not as much as I'd thought.
