Comic artist John Romita Sr., best known for his work on “The Amazing Spider-Man” and co-creating characters such as Wolverine, has died at the age of 93.

“He was the greatest man I ever met,” Romita Jr., who is also a renowned comic artist, added.

Born on January 24, 1930 in Brooklyn, Romita Sr. graduated from the School of Art & Design in Manhattan before spending eight years at DC Comics.

“Sorry to hear about the great comic book artist John Romita Sr passing at the age of 93,” wrote Gunn.

“My brother & I wrote Mr. Romita when we were young kids & sent him drawings of superheroes we were working on. He wrote us back, telling us what he liked about the drawings! A truly memorable experience in my life, making me feel like the magic of comic books, which seemed so otherworldly, wasn’t actually that far away. My thoughts & condolences are with his family & loved ones,” he added.
