Franklin McMahon's main artistic output was his 8,000-9,000 drawings. He also produced films and books. His films incorporate drawings , at a rate of 200–300 drawings per ½ hour of film. The books, although sometimes labelled as "illustrated" by Franklin McMahon, had the same kind of ["on site"] drawings as those from the courtroom, the political arena, and all his other spheres of activity. Even his commercial work had drawings mainly done on site, not after-the-fact illustrations for existing text.
