John P. D’Agostino Sr., better known as Jon D’Agostino, was a longtime Archie artist and the letterer on The Amazing Spider-Man #1.

D’Agostino was born in Cervinara, Italy on June 13, 1929, son of the late Pasquale and Annunziata Pitanello D’Agostino. He attended the Industrial School of Art in New York City. His first job was as the Head Colorist for NYC’s Timely Comics, the 1940s forerunner of Marvel Comics. There he supervised a new young artist named Stan Goldberg, who would later become one of Archie Comics’ most prominent cartoonists.

His mentor early on was the well-known Stan Lee. For the next 62 years, he did work for many comic book publishers. His credits include My Little Margie, The Amazing Spider Man, The Incredible Hulk, G.I. Joe, A Real American Hero, Teenage Mutant Ninja Turtles, Sabrina The Teenage Witch, and Sonic The Hedgehog.

In June 1965, Managing Editor Richard Goldwater hired D’Agostino away from the competition to join Archie Comics, where he was affectionately known as “Dag.” He continued there for over 40 years; working up until his death. One of his best-loved works at Archie Comics is “Jughead’s Time Police.”

D’Agostino’s last interior work was published in December 2010 in Jughead Double Digest #166, as part of the four-part “Cyrano Jones” story. D’Agostino’s work on covers continued to be seen throughout 2011 after his death.
