From the publisher:
Written and compiled by TMNT co-creator Kevin Eastman, this 296 page jam packed collection features over one thousand color and black and white illustrations, many of which have never been seen before. Sketches, character designs, page layouts, thumbnails, and final pages as well as a complete set of all of Kevin Eastman's original paintings of the fab four.
Eastman guides you through a dazzlingly, in-depth look at the creation of the Teenage Mutant Ninja Turtles. From the modest beginnings to the merchandising, pop-culture juggernaut, this collection has been "sold out" and hard to find for years. But now it's back in print for a new generation of fans to enjoy.
