Query: Toy Boats in a half-full tub...

This is a pretty good book on the subject. I gave it a four because I believe this is a worthy subject and needs more attention to details. In other words, the book, as good as it is, needs many more and detailed photos. Otherwise, perhaps, it could have added more info on the manufacturers and any history/interesting background on each model. The photos, as they were in number, are quite good in quality. I do recommend this book for anyone wanting a brief look at these samples of the toy boat.
