Nearly 24 years after his death, a new book by Dr Seuss is to be published from a manuscript discovered by the author's widow.
The author, whose real name was Theodor Geisel, was probably the world's best known children's writer and illustrator. His books have sold more than 650 million copies.
The manuscript for What Pet Should I Get? was discovered in a box at his home by his widow Audrey in 2013.
"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," she said.
Susan Brandt, president of licensing and marketing for Dr Seuss Enterprises, said she was alerted to the find by Geisel's long time secretary and friend Claudia Prescott, who was helping Audrey Geisel clear out the author's office.
"We had no idea what we were in store for when Claudia notified us of the materials discovered in Ted's home," she told Nine to Noon.
"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."
It is believed the manuscript was written between 1958 and 1962.
What Pet Should I Get? features the brother and sister from Geisel's 1960 book, One Fish Two Fish Red Fish Blue Fish.
She said the book dealt with the classic dilemma for children of choosing their first pet - and in true Dr Seuss style there were some unusual choices.
The book would be released in July, and Ms Brandt said there were enough treasures in the boxes to publish at least two more works.
