One of the koolest Christmas covers ever...
...which most people don't realize is a wraparound, since they've only seen the front and, as a result, don't get the joke!
This cover for Dell's Santa Claus Funnies #1 (1942) has never been reprinted in full!
I've seen the front cover in a number of reference books, but never the back one.
BTW, the reason Santa's driving a Jeep is that it's wartime, and the vehicle had just been introduced into America's Arsenal!
Though the artist is considered "unknown" by the Grand Comics Database, it looks a lot like Walt (Pogo) Kelly, who was working at Dell, and contributed a couple of stories to the book.
