One stone drawing slate patented by C.C. Shepherd, ca. 1877. The slate is contained within a wooden frame, which is supported at one end by a hollow wedge, used to store rectangular slats, which function as drawing cards with white and black illustrations. On the underside of the wedge is a paper label which reads: "Portable Slate Desk." The copy is placed in a direct line of the focus of the eye, so as to enable the pupil to see the Copy, and the execution of the same. ... Patented January 1877. C.C. Shepherd." At the top of the slate are slots where the rectangular slats slide in.
