I still have my T-square, protractor, straight edge, lettering guide, French curve, compasses, Rapidograph pens and an assortment of pen point thicknesses. I think I had enough different stencils to create "stencil envy" among my peers, exacerbated by the fact I had a drafting table made from a bulletproof window I salvaged from a currency exchange that was being demolished. Oh yes, don't forget the slide rule! I remember buying india ink by the quart. My first wife was an architect whose firm (Skidmore, Owings, & Merrill) was one of the first to use computer drafting software in the 1970s, but we still had reams of Zipatone (Sp?) at home for her to stick onto foam core for making models look like they had windows, or bricks, or any other repeated architectural detail. I remember buying Xacto blades by the hundreds for carving Balsa. posterboard, foamcore, and cardboard into 3D scale models. We bought rubber cement by the case in gallon cans.
In an average drafting studio, combining spirit duplicator (alcohol) smells and rubber cement thinner smells with the smells from the blueprint machine and three martini lunches, it's no wonder some draftsmen and engineers fell asleep at their tables in the afternoon!
