Al Jaffee's 'Fold-Ins', which have graced the back page of "MAD Magazine" since 1964, have become an icon of American humour, issue after issue, year after year, each fold-in requires the reader to simply fold tab A to tab B to reveal the hidden gag- a simple idea that masks both the undeniable artistic ingenuity and comic-timing at play in Jaffee's work. 'The MAD Fold-In Box' places Jaffee in his rightful place as the reigning clown prince of comic art.
