Alan Kupperberg is known for working in both comic books and newspaper strips, as if you weren't already aware of that fact.
Alan started his comic book career by writing dummy letters for various Marvel comics back in the late 1960s. In the early 1970s he began in the production department at DC Comics, working with the likes of Jack Adler and Sol Harrison. In 1974 he moved to Atlas/Seaboard comics where he spent time as a letterer/editor/colourist and working as a production manager. Once Atlas folded he returned to Marvel, this time as a fully fledged professional and began working on titles such as The Amazing Spider-Man, The Incredible Hulk, Iron Man, Captain America, Dr. Strange, Savage Sword Of Conan, The Rampaging Hulk, Transformers and many others. Enjoying runs on team books such as The Avengers, The Defenders and The Invaders, Alan showed his ability to draw several superhero characters in the one book. He also displayed his diversity with the title What If In 1978 he took over the Howard the Duck weekly comic with writer Marv Wolfman, at the same time he worked on the short-lived newspaper strip, The Incredible Hulk, a strip that many consider to be superior to the comic book that Marvel were publishing at the same time.
Alan is responsible for the highly successful one-shot comic, Obnoxio the Clown vs. The X-Men. Working virtually alone, Alan handled the writing, illustrating and lettering, unusual for the comic industry at that time. For a short while Alan appeared to specialize in nasty clowns, illustrating not only Marvel's "Obnoxio" pieces but also National Lampoon's "Frenchy The Evil Clown."
