Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
Judging from the other photos in the box with this, these people are either relatives or childhood/family friends of my mother, which would mean the pic was most likely taken in Salt Lake City or possibly Albuquerque, those being the two cities where she grew up. Unfortunately, those who would know for sure are no longer alive to tell me. I just found it an interesting pic, as you don't seem to see photos of less-prosperous-looking people in this time period very often, also I thought some Shorpyites might have fun trying to identify the various vehicles in the background.
