Eadweard Muybridge produced a series of 50 different paper 'Zoopraxiscope discs' (basically a version of the phenakistiscopes), with pictures drawn by Erwin F. Faber. The discs were intended for sale at the 1893 World's Columbian Exposition in Chicago. They seem to have sold very poorly, and surviving discs are quite rare. The discs were printed in black-and-white, with twelve different discs also produced as chromolithographed versions. Of the coloured versions, only four different ones are known to still exist (with a total of five or six extant copies).
