WTB: Old Large Hardcover Book

[aych]

I'm looking for an old large hardcover book for a project. book must be 3+in thick and at least the size of a letter page (8.5 x 11"). Its fine if its old and coffeestained etc. don't mind if its missing pages either, but must have the front and back cover in a decent condition. love it if its free, but if not please state your price.

thanks!
