Photostat of the cover is made, the logo added, and finally the color is laid in over this statted wash drawing", rendering a painted effect. Later comics career In late 1965, Grandenetti began freelancing for additional companies, drawing a small number of stories for Charlton Comics and Tower Comics, and penciling a Sub-Mariner story—inked by the character's creator, Golden Age of Comics legend Bill Everett—in Marvel Comics' Tales to Astonish #86 (Dec. 1966). Mostly, however, Grandenetti began turning to Warren Publishing, home of the black-and-white, horror-comics magazines Creepy and Eerie. Grandenetti's work for Warren, writes comics-art historian Don Mangus, "returned to a much more expressionistic and experimental phase, building on what he had begun at Eisner's studio, or perhaps due to freedom from Kanigher’s restraints. Perhaps it was the subject matter or the fluid nature of the wash medium but whatever the case, he produced brilliant work at Warren in the late 1960s and early 1970s". Warren would later reprint his youthful work for Will Eisner with the magazine series The Spirit. Grandenetti was profiled in Creepy #42, and a self-portrait ran in Vampirella #16. Concurrently, for DC, Grandenetti succeeded Neal Adams on the 1960s run of DC's supernatural spirit of vengeance the Spectre, drawing issues #6–10 (Oct. 1966 – June 1969). Grandenetti also helped revive the 1940s DC character the Phantom Stranger, drawing the lead story in his return appearance in Showcase #80 (Feb. 1969). In Showcase #82 (May 1969), he and writer Dennis O'Neil co-created the minor sword and sorcery character Nightmaster—originally assigned to then-newcomer Bernie Wrightson, who was taken off it after his first seven pages proved disappointing. He contributed to at least one issue of the black-and-white humor magazine Sick (#70, Oct. 1969), edited by his friend Joe Simon, the Golden Age co-creator of Captain America, then collaborated with Simon at DC on issues of Champion Sports. The two then co-created the youth culture oddity Prez, about the first teen president of the United States, and the one-episode Green Team: Boy Millionaires, in 1st Issue Special #2 (May 1975). Grandenetti penciled a parody of the TV series Kolchak: The Night Stalker in the Marvel humor comic Arrgh! #4 (July 1975), for which he also drew the cover. Comics historian Mark Evanier, calling Grandenetti "[o]ne of the great individual stylists of comic books in the fifties and sixties," wrote that, Grandenetti continued to freelance occasional stories for
