This story was originally intended for SANDMAN #7 in 1975, before that series was cancelled. A few years later it was uncomfortably squeezed into an issue of KAMANDI, which was cancelled before that issue, and only "published" in the photocopied CANCELLED COMIC CAVALCADE #2 in 1978. Finally, in 1982, it was included in this digest of Christmas stories.
Santa is unusually sarcastic on the last panel of this page:
Like all 1970s Sandman stories by Michael Fleisher, it doesn't make much sense except in a dream-logic kind of way. In this one, Sandman's young friend Jed gets a rich man to promise to give a million dollars to charity if he can prove Santa Claus exists. Jed enlists Sandman's help, and it turns out he's a friend of Santa, so they head off to the North Pole, pursued by the rich man's nephew, who isn't about to see his inheritance given away. At the North Pole, they find Santa has been kidnapped by the usually friendly Seal-Men, and go to rescue him, finding out that the Seal-Men were upset at the Christmas gifts they were getting, such as gloves (useless with flippers). They accept an apology for the mix-up, then Santa and Sandman take care of the evil nephew and everyone has a Merry Christmas.
Mike Royer inks the 18 page story.
