SOURCED FROM LIBRARY OF CONGRESS
If you recall, the original image found of Fedosimov was in 2016? Maybe a little later. The photo above, whilst basically the same, includes more detail. For example, each man has a briefcase and you get to see just a little of Pavel's shoe, left foot, what big hands he has.
The photo shows some staining and unusual marks but what caught my attention, in particular, is the man standing to the left of the shot who appears to be using a movie camera. The search is on to see if we can dig that clip out from an archive somewhere.
For the record, the photograph above was found under 'Nikolai Novikov' with no mention of Fedosimov in the file title.
