Carl Hubbell worked together with Norman Maurer at Joe Kubert at Lev Gleason, working on titles like Boy Comics and Whack, as well as other projects for St. John Publishing. In 1949-50, he drew the 'Merrie Chase' newspaper comic scripted by Renny McEvoy. Paul Reinman continued the strip in 1950-51.
Later on, during the 1960s, Hubbell inked several issues of Marvel's 'Sgt. Fury And His Howling Commandos' pencilled by Dick Ayers and 'Rawhide Kid', pencilled by Larry Lieber. He also drew for 'Captain Marvel' over at M.F. Publications.
