Here are two sketchbooks that I picked up at Spectrum that are awesome:

Stuart Ng (who is awesome for making these sort of books happen) is selling signed copies from his online store here. The drawings inside are amazing, insane, wonderful and terrifying. If I had it to do over again I would have bought 2. Or 3.

#2 Cory Godbey’s New Sketchbook: Menagerie.  

It is 44 pages of wild animals and incredible pencil-work. He also includes a number of really gorgeous studies inside. Check it out here.
