I was wicked fast on these back in the 80s. Rapidograph pens. India Ink. Ultrasonic cleaners. Mylar drafting film. Good times.
And then along came AutoCAD and entire industries and skillsets were made irrelevant.
I think I still have the paraphernalia somewhere…maybe tossed in with my dad's drafting equipment.
I really need to make an architectural shadow box. Or two.
