For example:
This photo-
http://www.gettyimages.com/license/515020819
is actually this photo:
https://www.flickr.com/photos/library_of_congress/2178341487
which was taken by a now dead photographer called Russell Lee, and owned by the Farm Security Administration.
PS: this same person appears to have about 500k listings for prints etc on amazon.com..... why aren't they a co-defendant?
