You can see this set at The Trading Card Database/Santa Claus - but that is all I know. Except that it is a lovely set, and I did not believe that such joyful innocence was celebrated any more. Three cheers for Topps for making me feel the spirit of Christmas.
Now a bit more information has been supplied thanks to our readers, including a link to the L.A. Dodgers - whose site tells us that the cards were based on baseball cards, I did not know that.
We also know that there are autograph cards available, of Santa himself, which are entitled "Topps Santafied Autograph". These are coded as SCA-SC, standing for Santa Claus Autograph and Santa Claus, which kind of made me wonder if there were, or might be later, other members of the Christmas story. There is also a card which has a piece of his suit attached thereto. Hope it was removed from a part where the winter wind will not chill him too much. This is coded SCR-SC, or Santa Claus Relic and Santa Claus.
Now in 2016 there was another set issued. This is called the "Santa Claus Holiday Set", and has nine cards, all but one of which has an autograph card too. Just as I suspected, the family has been expanded just from Santa Clauses, and an elf and a reindeer make their first solo appearances. As you might imagine, the reindeer was the one who did not sign their card, but I have to say that this is slightly lacking in imagination, because they could have put a hoofprint, or bitten a piece from the edge in a reindeer mouth shape....
