Vincent Joseph Colletta entered comics in 1952, freelancing first as a penciler, inking his own work, for Better Comics. In 1953 he began his decades-long collaboration with Marvel (then Atlas) Comics, primarily as a romance comics artist. During the Atlas “implosion” in the late 1950s, Colletta freelanced as a penciler on DC and Charlton Comics’ romance titles.
Historians pinpoint Colletta’s first inking of Jack Kirby’s pencils as either the cover of Kid Colt: Outlaw #100 (Sept. 1961) or the cover of Love Romances #98 (March 1962). He inked Kirby’s Fantastic Four #40-43, as well as Fantastic Four Annual #3, featuring the wedding of Reed Richards and Susan Storm. But their most well known collaboration was his six-year run on Kirby’s Thor, begun with the “Tales of Asgard” backup in Journey into Mystery #106 (July 1964). Except for one issue, Colletta inked the lead Thor story from #116-167, picking up again from #176 to Kirby’s final issue, #179 (Aug. 1970).
Colletta was regarded as one of the industry’s fastest inkers and a reliable professional to call upon when a comic was in danger of missing a printing deadline. He’s also Kirby’s most controversial inker; while his style suited the mythological setting of Thor well, he would later be criticized for eliminating details Kirby put into his work, both in order to lessen the inking burden and to help meet time constraints.
