Shirlie was generally straightforward about her photography. She manipulated photos for publication ... cropping them, highlighting parts of the image and blacking out backgrounds when they got in the way of the message. But these were part of the standard journalistic photographer's toolbox.
There were times where she played a bit more with the images, however. She had one at home that made her look like she was diving ... when actually she was standing on her toes and she printed the photo turned 90 degrees. For greeting cards she would embellish the prints and even use double exposure to make some pretty cool cards.
Only once have I seen a wrestling photo with a double exposure effect! This one from the 1950s where she combined two out of the ring fight images to hype up the action. Very effective. I think these are the Sharpe Brothers and at least one Torres or maybe Ronnie Etchison, but not sure. BTW, that's Glenn Neece trying to break them up.
