A new Dr. Seuss book to tickle your mind, take a peak at the pages if you're so inclined...

Grown dusty in a box was an original manuscript and sketches found in the home of the late children's author Dr. Seuss, aka Ted Geisel. It was turned into a new book with one million copies published July 28, 2015 by Random House Children's Books asking the immortal question -- "What Pet Should I Get?"

The box of sketches and text was found shortly after Dr. Seuss' death in 1991 when his wife, Audrey Geisel, remodeled her home.

Forgotten until it was rediscovered in 2013, the box revealed the full text and illustrations for "What Pet Should I Get?" among other gems. It may well be the first of three new books by the beloved children's author who produced classics remembered well past childhood.

The new story captures the excitement of a classic childhood moment -- choosing a pet. The little girl and boy face the perplexing quandary of choosing a cat, dog, bird or fish.

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.

Sixteen black-and-white sketches were labeled "The Pet Shop" with text taped to each drawing.

"We believe that he wrote and illustrated What Pet Should I Get? somewhere between 1958 and 1962 -- as the brother and sister in the book are the same as those in his bestselling Beginner Book One Fish Two Fish Red Fish Blue Fish which was published in 1960," said Goldsmith.

Colored pencil alphabet flash cards were found in the same box as the "What Pet Should I Get?" manuscript.

One of Theodor Geisel's sketches for "The 500 Hats of Bartholomew Cubbins," published September 1, 1938.

The book stood out from the majority of Dr. Seuss collection since it was written in prose rather than rhyming and metered verse that readers came to expect from the series.

"The Cat in the Hat" was published in 1957. The finished drawing shows Geisel's numbering system to indicate colors to be added later.

Referring to the new book, Audrey Geisel said, "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. 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!'"

A colored sketch of "Sam I am" from "Green Eggs and Ham," published August 1960.

It is listed by Publishers Weekly as the fourth best-selling English language children's book of all time.

Dr. Seuss's "The Cat in the Hat" is another classic, first published in 1957 and turned into a movie and TV special.

"How the Grinch Stole Christmas!" published in 1957 was a critique of the commercialization of Christmas.

Theodor Geisel initially pursued a career in advertising.

Geisel transitioned to working as a political cartoonist for the New York newspaper PM.

During WWII Geisel worked for the animation department of the U.S. Army.

Geisel's war bonds ads clearly shows the emergence of his drawing style and one can see the similarities to characters in his Dr. Seuss books.

American author and illustrator Dr Seuss (Theodor Seuss Geisel, 1904 - 1991) sits at his drafting table in his home office with a copy of his book, "The Cat in the Hat," in La Jolla, California, April 25, 1957.

Geisel created many of the of the best loved children's book of all time.
