Theodor Seuss Geisel passed away 24 years ago, in 1991, at the age of 87, but the name Dr. Seuss is still very much alive in the world of young children reading his books.

A new Dr. Seuss book titled "What Pet Should I Get?" is set for release on July 28, USA Today reports.

The book, as Seussville describes, captures one of the most difficult decisions everyone makes in their childhood-choosing a pet. 

Just like the historic discovery of Harper Lee's "Go Set a Watchman", the manuscript had been written a long time ago but had only been found very recently. The editor's note at the end of the story also discusses how the manuscript turned up only about 20 after the last published book.

According to New York Times, Geisel's wife, Audrey, decided to have their house in La Jolla, California renovated. Some valuable possessions, including early illustrations and drafts, of the late author had been donated to the University of California. Other abandoned sketches had been stashed in a box with the help of an assistant.

While the box was filled with abandoned and unplaced notes and illustrations, the value of the contents never faded.

In October 2013, they decided to have the rest of the contents appraised and examined them carefully. The box really contained abandoned notes. A folder marked "Noble Failures" contained illustrations that never found their right place in any story. Within the contents, they found a set of pages marked "The Pet Shop". It contained black-and-white illustrations and typed text.

On the stained and discolored pages lies a story that is more than two decades old.

"We didn't know that we had such a treasure," the assistant told New York Times.

USA Today further reports that the publisher, Random House Books, intends to publish two more books based on two more materials found in the box.

The Dr. Seuss Facebook Page is currently making countdown posts for the release of the book. Each countdown posts features a trivia about Dr. Seuss books.

One of the books featured is "The Butter Battle Book." The author ended the story with an open ending. When the book was released, readers started imagining their own endings and submitting them to Dr. Seuss.

According to another post from Seussville, Theodore Geisel's first book had been rejected by about 30 publishers before getting printed. He has now authored more than 40 books including the classics "The Cat in the Hat" and "Green Eggs and Ham".
