About this work

A color lithographic chart from 1920 by P. Krüger presents labeled illustrations of historical friction and static electricity apparatus, arranged in lettered panels. The devices include a glass plate machine, a Leyden jar, a Guericke sulfur globe machine, and small electroscopes, each annotated with the name and year of its inventor. The sheet is a print with a cream background and a bordered layout.
