Simplistic for its time, still an interesting series that debuted in Six-Gun Heroes #57 (June, 1960) and ran through issues #83 (March-April, 1965), along with two runs of self titled series, one for four issues (#1 to #4), and the second running for 6 issues, picking up its numbering from Six-Gun Heroes, though Giordano didn't do covers for the whole series, the ones he did are below.
Gunmaster was Clay Boone, a gunsmith who travelled from town to town with a small arsenal, dispensing justice with lead in his masked identity. He even added a sidekick, Bullet the Gun-Boy (who was Bob Tellub) in Six-Gun Heroes #79 (March, 1964), and faced foes like Doctor Dynamite and various other thugs and cattle rustlers.
