From a press release:

BALLANTINE BOOKS TO PUBLISH BOOK INSPIRED BY THE WEBCOMIC GARFIELD MINUS GARFIELD

Collection to be published simultaneously with Garfield 30th anniversary book

NEW YORK, NY – July 30, 2008 – Paws, Inc. and Ballantine Books, a division of the Random House Publishing Group, announced last week at Comic-Con International that Ballantine will publish a book inspired by the popular webcomic Garfield Minus Garfield...

The full-color book format will give readers the experience of having both the original and doctored Garfield strips together on the same page for comparison. Dublin, Ireland-based Garfield Minus Garfield creator Dan Walsh will provide the foreword to the book.

Garfield creator Jim Davis was intrigued by—and pleased with—the concept. “I think it’s an inspired thing to do,” Davis said. “I want to thank Dan for enabling me to see another side of Garfield.”
