Neal Adams - Original Art for Archies Jokebook #46, page 2 (Archie Publications, 1959). Published in 1959 and drawn when the artist was a mere 18 years old, this is Neal Adams' earliest known page of comic art! Adams revolutionized comics in the 1960s and 1970s, bringing dynamic realism to the forefront of comic art style. His influence is still felt today in many of the industry top talents - he is arguably as important and influential to his generation as Jack Kirby was to the generation before. From Archie's Jokebook, offered here are two half-page stories on one board. Adams himself has identified this page as his own work in his catalog on nealadams.com. The page, which is in excellent condition, measures approximately 13.75" x 18.75" overall, and displays minor use of white-out in several panels. Additionally, the logo stats for "Archie" and "Jughead" are missing, but that detracts not at all from the beauty of this great page from one of comic's most influential artists.
