Staff from Udon, including Matt Moylan, their Director of Publishing, have shown off what the book looks like inside from their own advance copies as the product goes on pre-order.
Udon expects the book to be available from Amazon starting May 3rd, 2017. With Amazon listing a price of $31.12 for the book (which is a 152 page hardcover.) (Amazon meanwhile is claiming July 11th, 2017 for release)
Matt Maylon has indicated it is possible for art books for the spinoffs to be made provided the first book is successful.
It’s also noted the art was upscaled in the book as far as could be possibly done without reducing the quality of the images.
