Spoofing fold-outs featured in Playboy, Jaffee created "fold-ins" featuring an image and a question.

 Starting in 1964, virtually every issue of Mad over the next five decades featured new material by the artist. Jaffee’s work parodied advertisements that featured future real products, such as spell check and redialing for phones.

Spoofing fold-outs featured in Sports Illustrated and Playboy magazines, Jaffee created "fold-ins" featuring an image and a question. When folded, it created a new image and the answer to the question.

"A humble and kind creator, Al’s presence, his astute social commentary, and his endless amusement at life’s ups and downs shaped the fabric of the magazine," the magazine said in an Instagram post.
