This paper pop-up with authentic Masonic symbols was created by Guy Spivey, a member of a Scottish Rite lodge in North Carolina. Spivey intended the pop-up to be a 3D "Trestle-Board". A Trestle-Board is a board mounted on a trestle (easel) on which architects in ancient times drew their building designs. In Masonic lodges today, Masonic symbols are drawn on Trestle-Boards instead of architectural designs. Instructions and a template for this pop-up may be found here.
