I had almost all of the Jean Auel's books and needed this one to complete my collection. It turned out to be a book club size and I traded it to a friend for the full size version.

Positive

question:
A wonderful pictorial book about transistor radios, 175 of them, not only photographed but put in the context of fifties and sixties design. The spread on 60-61 shows six radios mixed with close-up photos of chrome styling from fifties cars. I loved the chapter on design with its photos of grills and lettering, even a spread on 9-volt batteries.This is the kind of book that Chronicle do so well, interesting subjct, well designed and printed all for the general reader. If you collect these radios you will certainly want to have a copy but don't expect to get lots of technical detail or a price guide. For that have a look at 'Collector's Guide to Transistor Radios' by Marty and Sue Bunis, plenty of text about seven hundred models, some photos and that all-important identification and price information.

If you are not in really good shape this is a great product to get ready for P90X. It does get kind of boring because you are doing the same workouts every other day, but they do work. It is only about 30 mins but it is amazing how well it works.

Positive
