(I posted a different version of this, with no response as of writing, in r/Russianhistory)

Does anybody know the source or provenance of the famous photo that Yezhov was removed from? The photo is extremely common on the Internet, being nearly universally used to illustrate the concept of a "nonperson" (it's the main image on the Wikipedia page of that name, as well as on Wikipedia pages titled "Joseph Stalin," "Nineteen Eighty-Four," "Photo manipulation," "Airbrush," "Censorship," "Marxism-Leninism," and many more).

The version hosted on Wikipedia (which itself is reproduced on numerous other web sites) is from this article on the Tate's web site, which attributes it to "the David King Collection," which own many Soviet-era images: http://www.tate.org.uk/context-comment/articles/revelation-erasure

Does anybody know who initially publicized this "before and after" photo sequence, and when? Where might it have initially appeared in print, either before or after Yezhov was removed, and when they would have appeared side-by-side?
