Bodyscape

The wonderful cover of a graphic wheel from 1948

Volvelles, or graphic wheels, are devices consisting of a series of movable discs that collate a large amount of information into a compact delivery device. The contents of Bodyscope—shown here in its fourth edition—are presented on four, pierced card sleeves, with a turning disc inside. Each of the four "pages" has three pierced sections containing five subjects on the rotating disc beneath. Each page focuses on a different physiological area and includes both descriptive and explanatory passages for each organ system.Volvelles like Bodyscope were popular from the 1930s to the 1960s
