I used a photo of Soo Catwoman as a reference when I painted, the original picture is from 1976, the photographer to the picture is Ray Stevenson. He is one of the few who took really good photographs on e.g. Sex pistols and other bands. I have received this picture as a personally approved consent from him to post. You can see his fantastic photographs from the historic start of Punk Rock here in his link.
Thanks Ray!
