This is an advertisement for Coca-Cola which appeared during the Christmas season in 1964. Santa has lots of ideas for the holidays and they could be found inserted in cartons of Coke. The ad reads as follows:

Hey, what a great promotion for dealers! HOLIDAY IDEAS IN CARTONS OF COKE. Colorful folders pre-packaged in each carton, just loaded with decoration ideas, festive food settings, holiday hints ~ all kinds of things to make extra profits and merrier holidays. Hm! Who says there's no Santa Claus?
