i have a collection of old schoolbooks. i used to find them all the time at garage sales for $.25 or less, and theyre mostly all beat up, but i like them. Most have doodles in the margins and all kinds of wriitng, but its interesting to see what countries were around in the 20's and what has changed. the history books are also fun to read, as there is much less of it(wwi is "the Great War", etc.). basically they are worthless, but look great on the top of my old upright piano.
