This is a black-and-white advertisement most likely from TV Guide. You see Charlie Brown looking sad as peppermint Patti scolded him for the weird meal that Snoopy, who is on the right wearing a chef’s hat prepared for their Thanksgiving dinner. Each plate has several pieces of toast, jellybeans, pretzels, and popcorn. This is an advertisement to watch a Charlie Brown Thanksgiving holiday movie it was sponsored by Peter Paul and McDonald’s.
