When Cap'n John (founder of the Paper Heroes chain of comic shops) saw my photo of last year's Bongo Christmas Poster, he recognized the art from a Bongo Christmas Card he'd received back in the early '90s. He dug it out of his Big Box o' Nostalgia for me to scan (see below), and also stumbled across this Diamond Comics Christmas Card (above) in the process.
The front of the card shows Bart carving the Diamond Comics logo into a frozen pond with his ice skates. The inside shows the consequences for a cyanotic Homer.
Think of this post as an After Christmas Sale: Click on the images to enlarge, and save 'em for the 2006 holiday season.
