This should have been included in my previous post.

Flickr has partnered with the Library of Congress in something called the Flickr Commons. The LOC has team allowed the photo sharing site to use 1,500 of its photographs (from its 1 million page catalog) on Flickr.

The more important part of this is the fact that the LOC is asking for your collaboration –to tag the photos.

This particular photograph is from a series from the Bain News Service, from 1910-1912.

Thanks for Hyperbio for this.
