The book a 8.5 by 8.5 inches paperback. The purchase link points to Lulu.com so this looks like a print-on-demand book. The paper used is the copier type paper and the binding looks good. Shipping for the book is not going to be cheap because it's a heavy book. It's currently selling at USD $35 and for 600 pages I think it's worth the money.
The sketchbook collects 4 years of work from 2010. There are designs for characters, props, creatures, vehicles and buildings. The style is comic-style line art with a strong sense of caricature and whimsical touch. The art is beautiful and when you're looking at such a thick volume, it's awe-inspiring.
If you're someone who likes sketchbooks, comic art, 2D animation style art, you should check out this book.
