This reprint of a 1972 book is the best (and only) source of information on 35mm cameras and photography (which was called 'miniature' format back when most cameras used glass plates and/or large sheets of film). There is a short history lesson of photography from just before 35mm cameras became popular through the 1960s, then information about the cameras forms the bulk of the text.
Information on American 35mm cameras from this time period (~1920 - 1960s) is hard to find. This book describes the companies and their products. There are many photos, but they are of low quality (copies of copies), but when you are the only source who can complain? And at almost 350 pages this is a lot of information for the money.
A great book about a neglected subject. Highly recommended, despite the poor quality illustrations.
