Here's a quick crash course on animation, courtesy of Dell Four Color Comics #1183 which featured an adaptation of 101 Dalmatians. This special feature appeared on the inside back cover of that comic book and was in many ways a storyboard of the making of the film. The xerography process, pioneered on 101 Dalmatians, was even mentioned. Al Hubbard provided the art for the one one-page feature; the text is uncredited.
The issue included the 32-page adaptation of the movie drawn by Hubbard. The inside front cover showcased black and white stills from the film and a summary of the story. The back cover featured Dalmatian Diary, a history of the breed as told by Pongo and also illustrated by Hubbard.
