Query: Turn on to this radio book.

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.
