Great book. Originally in German so you know it's spot-on. Without this book you might as well give up your dream of showing Dave Letterman your rock collection. With it you have a chance. Maybe Dave will call Paul over. "Gee, Paul, this is a real pretty one. We've got to have this gal on the show again. An hour just isn't long enough." Hard cover. 8 by 5 inches 300 pages
