Isaac Kremer/ June 21, 2019/ / 0 comments
A metal pin used to fasten a drawing or sheet of paper, tracing linen, or the like, to the drawing board. It has a broad, flat head, a very short round shank or stem, and sharp point. The head is so beveled or slightly rounded at the edge that the T square and triangle slide easily over it. Called also drawing tack and thumb tack. (Sturgis, 1900)
