The back of a page from a sketchbook, with minimal editing, featuring a silly attempt at developing a personalized hanko, eventually resulting in an abstract of a hamster in a wheel, as seen at the bottom left, a few odd sketches, and this rather long sentence fragment.

Note that, in that link which sort of explains what a hanko is, you can save one cent by purchasing a square stamp, rather than a round one.
