Bill Layne’s pinup witch, 1966
Bill Layne was a background artist for Disney from 1942 until 1974 (working on, among others, Sleeping Beauty (1959), Mary Poppins (1964) and Bedknobs and Broomsticks (1971)). He did calendar advertising art for Brown & Bigelow and produced the following October/Halloween witch for a 1966 Esquire calendar.
Layne is not well known (he lacks a Wikipedia entry), certainly not as well known as Alberto Vargas, Freeman Elliot, George Petty or Gil Elvgren (the subject of previous posts); however, there are a few galleries online: this gallery has 18 images; this one has larger, but fewer, images. You should also check out Becca’s post on Layne at No Smoking in the Skull Cave, then bookmark the site and set aside a weekend to browse through the rest of her posts!
