That question ever come to mind when you're reading a Bridgman book?
Yes, they're great books, but sometimes I really can't tell if I'm looking at a tendon or tortellini. (No, not seriously) But his work is really scratchy and sometimes hard to read, at least for me.
Had the original works aged a bit before they were reproduced, or is it the material he drew with? (I think it's charcoal.)
CASE & POINT: I like Loomis better, even though it's impossible for me to own a physical copy of his books for the time being.
