I was wondering if anyone knew anything about these photographers. I read a short description of their work in the book "20th Century Photography" that stated that in 1984 these men, "created the cycle Masterpieces of Photographic Art, which proved that some of the most famous pictures in the history of photography, such as Irving Penn's portraits of Pablo Picasso, can be attributed to unknown, only recently discovered predecessors."

I just wanted to know if anyone has any additional info, i.e., did someone really do this (and other famous photographs) before Penn (and others) did them?
