Golden Age of comic books
Giella later freelanced for Fawcett Comics, commuting by bus to C. C. Beck's and Pete Costanza's studio in Englewood, New Jersey, to ink Captain Marvel stories. In either 1946 or 1947, he began freelancing for Timely Comics, the 1940s precursor of Marvel Comics, and shortly afterwards joined the staff. His start was rocky, however; as a 2012 article related,
"What he needed was a regular paycheck, so he kept dropping by the offices of Timely Comics ... hoping to get a job. [Editor] Stan Lee rewarded his persistence with a tryout inking a strip that cartoonist Mike Sekowsky had penciled. Giella's elation on his trip home soon turned to panic. 'The first job he gave me I lost on the train. No one slept at my house that night,' Giella jokes. 'I went in the next morning and thought that's the end of my job.' He was nearly right. As a frantic Lee screamed at Giella for his carelessness, Sekowsky came to his defense. 'Mike repenciled the whole job that I lost on the train and I did the inking,' he says. 'Stan liked what I did and I got the staff position. I never left anything on the train again.'"
"I would do any work that they offered," Giella had recalled in a 2005 interview. "I started out doing a little touch-up work, a little background work, a little inking, redraw this, fix this head, do something with this panel".[5] Later, he assisted Syd Shores on Captain America Comics, finishing backgrounds, making pencil corrections and inking occasional pages. Giella did similar duty on Human Torch, Sub-Mariner, and humor stories. Inking soon became his specialty. In 1948, he joined the Naval Reserves, continuing with them for eight years.[2]
His friend Frank Giacoia began drawing for DC Comics in the late 1940s; Giella joined him at that company in 1949.[1] There, Giella inked stories featuring the Flash, Green Lantern, Black Canary and other characters under editor Julius Schwartz.
