I've been doing a lot of sketching recently and thought of a comment my ID drawing teacher made a few years ago after I drew a rectangle behind one of my sketches, he said "Oh that's the old American style".
I know we're all sketch in different ways, but different ages seem to have certain trends, especially in the automotive industry. My curiosity got the better of me, so I looked into ID sketching history, but I can't find any resources on the historic progression of design drawings.
Does anyone know if there are any accounts on the history of design sketching/ idea generation?
It seems like an idea for a good coffee table book and a good resource into the concerns and practices of designers historically.
