I've posted about this site and its artist before (and, to be clear, it is not me...I'm just a fan) - it's Pop Fly Pop Shop.
Every week the artist (Jacob Daniel Horine) releases a new comic book style baseball print that is available for one week only, after which it is never reprinted. The total number of a given print is based on how many are sold during that single week.
Many prints relate to modern baseball, but he definitely dabbles in vintage as well, including pre-War. And, because this week's print of Christy Mathewson was just released, I thought I would mention it here in case anyone is interested. These prints are generally pretty amazing, but the one caveat is they usually take a month+ to ship given he doesn't have them printed until all orders for the week are in.
Anyway, please move/delete if this isn't the right place for this! Here's the link:
