Bill. A great range of cameras which I think give this shot a certain unique quality. It's as if it identifies a short period of time when this range of camearas might have appeared in the same shot. It could never be replicated. My guess is early to mid 1950s.
The photogs all seem to be dressed the same way. Are they professional full time press men? My guess is not. Military maybe? I get the impression they are not rivals but maybe a fairly close knit group as you's get in the military.
What are they about to photograph or just have photographed?
The name Werner Bishof gove me no clues as I have never heard of him.
I am interested to hear more about it. Thanks for posting.
