Paul,
It's REALLY hard to pick one. Incredibly so.
Lately, this has been my favorite:
It pictures the Wheeling Nailers playing a game on May 19, 1887. Something about having such a clear panoramic of what the game was like in the late 19th century, with players actually not posing, is really appealing to me. This is actual game action. I feel like it harkens back to some of the origins of the game most fans hold dear. Just a small town game with a couple hundred fans when the professional game was still somewhat of a new thing.
But then again, some of the great Tomlinson cabinets are friggin' incredible. I wanna paint them all.
