Over 50 women telephone switchboard operators and their supervisors. During this period (circa 1914), only young women (not men) were hired for this type of work at a Salt Lake City, Utah company. Men were not considered "polite" enough for this kind of work :)
This image comes from a group of vintage images that I purchased -- all are scanned from contact prints made from the original 8x10 glass negatives. I have performed extensive restoration work on each image, but trying to be true to the original.
