Santa Claus Conquers the Martians: The Comic Book
Now being sold on EBay by someone with a wry sense of humour:
"The book includes this disclaimer 'The events contained herein are fictional, and any resemblance to any person, living or dead, is purely coincidental.' So don't say you weren't warned. Santa Claus DID NOT in fact actually conquer the Martians; even though he probably wanted to. I hope that revelation does not detract from the suspense of this tome, and you still will bid with confidence. "
