I stick by my version.
In Britain in the early 1970s there were certainly racy images and bare breasts in tabloid newspapers. Indeed, it was this vulgarity which persuaded my mother to switch from the Mirror to the staider Daily Mail.
I was about 14-15 when I saw the article which makes it '72-3.
Hitler is on the right of the snap, looking serious and manic, and his right hand is raised in the 'elbow high' type of acknowledgement salute which he does on film sometimes.
The girl is barebreasted and dressed, as I thought at the time, as a stripper or stage-style dancer.
H's hand is not cupping her breast, it's more as if he was saluting and her boob got in the way! I don't remember an elbow in a crotch but the picture seemed close-up so could have been cropped. She could have been sitting on his lap.
This was a long time ago and I only remember it because it made such an impression on me: my parents had lived through the war and were still very much in an anti-German mode, a bit like Basil Fawlty. Any mention of Hitler (topical at the time as there were rumours of him still alive in S. America) made them extremely angry.
Don't we know any theatre history types who'll know about this?
There would have been lots of publicity photos taken and it's possible that 'my' snap isn't exactly the same as Rev's, but I'm certain it comes from the same source.
And of course, the whole nature of theatre is the creation of the illusion of another time and place.
'Cabaret', anyone?
Anyway, that's all I know and can't add any more to the discussion.
