I've got a folder on my harddrive labeled "Comics in the World" where I've shot pics of comics-related items in the wider world. Here's a selection from Rehoboth Beach, Delaware.
Louie's Pizza interpreted a Mad magazine cover from June 1976 for decoration.
Disney's Cheshire Cat from Alice in Wonderland on a car hood.
Dr. Seuss prints on sale in a gallery. Supposedly signed, they weren't. I'm sure these were printed after his death.
Simpson's Kooky Carnival pinball game.
