Pat The Bunny

Pat the Bunny (officially styled as pat the bunny) is a "touch and feel" book for small children and babies and has been a perennial best-seller in the U.S. since its publication in 1940. It is not a book in the traditional sense, but more a collection of things to do, such as pat the fake fur of a rabbit on one page, feel a bit of sandpaper that stands for "daddy's scratchy face" on another, and look in a mirror on yet another.

It was written by Dorothy Kunhardt, who was a successful children's author when she wrote Pat the Bunny for her 3-year-old daughter, Edith. It was partly an experiment in using interactive elements in a book, which was unusual at the time.
