Post 3000 Pencil Pointer

Description
This pencil sharpener consists of a flat wooden handle glued to a rectangular pad of sandpaper. The end of the handle has a hole for hanging. The back of the handle has a yellow label marked in black: POST'S (/) CHICAGO (/) No. 3000 (/) PENCIL POINTERS. The Frederick W. Post Co. sold this model of pencil pointer with 12 sheets of flint paper for 9¢ in the 1930s. By 1949, the flint paper was replaced with sandpaper.
William J. Ellenberger (1908–2008), who owned this object, studied electrical and mechanical engineering at The George Washington University between 1925 and 1934. He then worked for the Potomac Electric Power Company and the National Bureau of Standards. During World War II, he served in the U.S. Army Signal Corps. He was a civilian construction management engineer for the army from 1954 to 1968, when he became a private consultant.
