Robertryan Cory has the smoothest most rubbery, tubular, pinched-eyeball encrusted section in the brand new GO FOR THE GOLD! 3 sketchbook anthology (preorder here, preview here). He has been posting these amazing pages that were he rejected for inclusion in the book on his Flickr account.
EDIT: Attention GO FOR THE GOLD enthusiasts! I was aware of one order yesterday that a customer had an error with so today I said OK screw it and I gutted the whole store and redid it quickly with straight-up paypal buttons. If you tried to order and it didn’t work before, now it will work in a slightly less high-tech way. But it will work. Order away!
