Not the same but a similar type of thing, I recently picked up 'Motown: The Golden Years' by Bill Dahl...it's a great book featuring all the Motown artists with great 60's photos. Back section is dedicated to the 'unknown' artists. There's a colour section with photos by Weldon A. McDougal III who many know as one of the 'Harthon' production team. He worked with Motown artists during the late 60's/early 70's.
The one downside to it is the cover is awful (imo)...instead of using some stunning 60's pictures...they've opted for a few of McDougals (casual) 70's pics.
If anyone's interested, the book is published by 'Krause Publications' (www.krause.com)
