I don't have a drawing to contribute today, but check out my cool birthday present (a gift from myself to myself):
It's HUGE! The pages are the same size as Jack's original art--a ginormous 15" x 22." They're direct scans of the originals, so they come with all the marginalia, paste-up and corrections--you can even see the underlying blue-line grid (tho' it seems more light gray than blue on a lot of the pages).
p.s. I love all the new, original TAG content! Inspiring!
