A snapshot with that kind of work done on the background? That would be unusual. This looks like something I've seen on the board before--maybe Wheaties or Worch? The cutout style looks like some of the Worch items in this thread:

Given the location of the show, I'd say that Columbus Redbirds is a reasonable guess.
