Cartoonist Jack Davis (1924-2016) was, from all accounts, a gentlemanly soul, but he did have a knack for getting into trouble. When tasked by the United States Postal Service in 1989 to render a stamp commemorating its hard-working men and women, Davis came up with a drawing that some high-placed functionaries worried was insufficiently respectful. Hadn’t anyone told them that Davis was one of “the usual gang of idiots” on the staff of Mad magazine? Irreverence was the soul of the man.
