Al Jaffee, the longtime cartoonist for Mad magazine and creator of its distinctive back-page Fold-In, died on April 10 in Manhattan, the Washington Post reported. He was 102.

Jaffee, well known for his self-portraits in his Mad cartoons, as well as recurring series like “Snappy Answers to Stupid Questions,” was Mad’s longest-tenured contributor, appearing in the magazine from April 1964 to April 2013. Only one issue was published in that span without new, original work by Jaffee, according to a fan page keeping track of such appearances.
