This classic toy was constructed from the smooth sturdy cover of an old hardcover book. It has the solid feel and satisfying sound of a wooden version of this toy, while retaining the supple softness of the book cover it used to be.

True to its ancient design, this toy will amaze and confound children of all ages.

Formerly "A Guide to PL/I" by Seymour Pollack and Theodor Sterling
