Jack Davis, 91, an illustrator for Mad magazine’s “Usual Gang of Idiots” for decades, died Wednesday on St. Simons Island, Ga.

His other work includes posters for “It’s a Mad, Mad, Mad, Mad World.”

He began in 1950 selling drawings to EC Comics, which published “Tales From the Crypt.”

In 1952 Mad magazine began with Davis in the “Gang.”

Navy veteran Jack Burton Davis Jr. was born in Atlanta on Dec. 2, 1924, the only child of schoolteacher Callie Davis and salesman Jack Davis.

The National Cartoonists Society honored Davis with a lifetime achievement award in 1996 and he was inducted into the Society of Illustrators Hall of Fame in 2005.
