Query: A Disapointing Secondary Source with a Hobbiest's Opinion.

The ever increasing genre of self-professed "experts" produces yet another book. A gathering of undocumented black and white photos, with a hobbiest's "expert" opinion. After spending the money for this volume, I tried very much to like it, but could not. Readers will need to head to a museum or library for primary research and documentation.
