At his peak, each issue of "Mad" typically carried three Martin strips of one or two pages each. But Martin also did several longer pieces, including parodies of poems by writers like Longfellow, Coleridge, Edgar Guest and Clement Clarke Moore, thematic collections of gags on a single subject such as Moses, superheroes or Dracula, as well as full parodies of the "Gentle Ben" TV series and the films "Excalibur" and "Conan the Barbarian". He also drew some insert bonus material for "Mad Specials" such as stickers and posters.
