Clarke, Bob
Bob Clarke's elegant line appeared in innumerable advertisements as well as MAD Magazine. One of Clarke's early job was as an uncredited assistant on the "Ripley's Believe It or Not" comic strip. Years later, he would illustrate MAD's occasional "Believe It or Nuts!" parody.
Clarke was one of the artists who took up the slack after original editor Harvey Kurtzman left Mad. He was a mainstay of the magazine during its best years, being one of four general-purpose artists who took Mad through the late 50's and early 60's.
