A circa-1966 industry ad for Leon Maurer’s Animascope process for producing animation on the cheap: animation without drawing and with fewer pesky artists! Similar to but different than rotoscoping, this process used high-contrast photography and actors in contrasty costumes with their skin painted white and contour lines painted on. The performers would then be filmed dancing around under bright light on a black-lined stage, and the resulting photography could be composited onto traditional background plates. Weird, but sort of a primitive version of mocap, and done for the same economical reasons.
