Earlier this year it was reported that an original manuscript written by Dr. Seuss, aka Ted Geisel, was found in the La Jolla, California home of the popular children’s author. The book was “What Pet Should I Get?” and it’s already off to a terrific start.

Following its dramatic discovery, it was announced that Random House Children’s Books would publish the work along with original illustrations created by the Dr. Seuss himself.

Ted Geisel died back in 1991, the manuscript was found by his widow, Audrey Geisel, during a remodel of her home. The book was found in the fall of 2013 by Mrs. Geisel and Claudia Prescott—Ted Geisel’s longtime secretary and friend—when they were cleaning out his office space

This will be one of three new books that will be published from the materials discovered, the other two titles and publication dates will be announced at a later date.

“While undeniably special, it is not surprising to me that we found this because Ted always worked on multiple projects and started new things all the time—he was constantly writing and drawing and coming up with ideas for new stories,” says Audrey Geisel. “It is especially heartwarming for me as this year also marks twenty-five years since the publication of the last book of Ted’s career, Oh, the Places You’ll Go!”

“We had no idea what we were in store for when Claudia notified us of the materials discovered in Ted’s home,” says Brandt. “Pages and pages of manuscripts and sketches were laid out on the big glass dining room table. It was truly a magical moment, and we immediately knew this was more than just a box of sketches.”

The text and illustrations for What Pet Should I Get? were found nearly complete. Geisel traditionally completed his black-and-white line art illustrations first, with color to be filled in later.

WHAT PET SHOULD I GET? captures the excitement of a classic childhood moment—choosing a pet—and features the brother and sister characters that Dr. Seuss introduced in One Fish Two Fish Red Fish Blue Fish.

The discovered materials will be kept at UC San Diego, where the Dr. Seuss Collection is housed within the Geisel Library.

The book has rocketed to the top of the charts on online retailers since its discovery. The book will release on July 28, 2015 and is already at the #1 spot on Amazon’s list of best-sellers in the ‘Poetry for Early Learning’ section.
