I get asked occasionally what kind of pencil the great comic book artists use. Answer: All different kinds. When I met Steve Ditko in his studio in 1970, I asked him what he was drawing with and he showed me. It was a pencil that only said on it "Chemical Bank."
A lot of artists though like Palomino Blackwings. This is not a breed of horse. As this article explains, it's a popular kind of pencil.
