Mortimer began working for DC Comics in 1945, and quickly became a cover artist for comics featuring Superman, Superboy and Batman. His first known comics work is as the penciler and inker of the 12-page lead Batman story, "The Batman Goes Broke" by writer Don Cameron, in "Detective Comics" #105 (Nov. 1945); contractually credited to Bob Kane, it is also signed "Mortimer." The introduction of Batman's Batboat in "Detective Comics" #110 (April 1946) was another Cameron/Mortimer collaboration. Mortimer launched a Robin feature in "Star-Spangled Comics" #65 (Feb. 1947).
