We’re sad to announce that on Sunday, legendary MAD artist Bob Clarke passed away at the age of 87. Bob was with MAD nearly from the start — first contributing in 1956 and continuing through 2010. During his amazing career as one of “The Usual Gang of Idiots,” Bob was one of the magazine’s most versatile artists, illustrating everything from covers, to articles, to Spy vs. Spy, to bonus inserts for MAD Specials (including the MAD Zeppelin paper model and the MAD mobile). Bob’s contribution to MAD’s legacy is massive and he’ll be greatly missed. As a way of honoring him and saying thank you, we’ll be showcasing some of Bob’s best MAD work throughout the day.
