The shape of it when I first saw it made me think of a hornbook (a small paddle of sorts, usually bearing an alphabet, used for teaching; one day I will find an actual hornbook! ) Anyway, I find it quite satisfying just as an object and could not put it down.I also like the 0-10 scale; it could be used now for judging gymnastic routines! \u003c\/p\u003e\n\u003cp\u003e4\" x 1 1\/4\" x 1\/8\". Very good condition, great patina, late 19th c.\/early 20th c.
