This book was disappointing. It's title lead me to believe that it would be an extensive and thorough compilation of most, if not all of the bikes Schwinn produced; not so!I own a 1970 Schwinn Twinn Tandem bike, and was hoping I would read and see information on tandems. They picture one tandem, and have very little information about it. They also fail to depict several other models. If you look at an orignal Schwinn catalog, you'll find that they built dozens of models each year! Do a google search and you'll find it.One of Schwinn's more popular models was the "Typhoon", and I don't even see a mention of it! What a crock!I have a Standard Catalog of Corvette, and it's is much more thorough than this one for the bike.
