The person who uploaded this image to Wikipedia should have been polite enough to credit the source: the David Sarnoff Library website, where it was uploaded after I discovered and scanned the the only extant paper version of the photo between 2001-2.[1] The watermark on the bottom right represented the Library's creation of the digital scan, but is hardly a form of recognition by users. We asked through the FAQ page,[2] that people using photos for non-profit uses to please credit the Library:
"Can I copy the pictures online?
"Please feel free to copy images for educational assignments. We ask however that you credit the David Sarnoff Library for visual or written material that you use, and that you cite the relevant webpage and date of visit. If you would like to use images on your website, please link to the images, and let us know of the links."
