I have discovered the name of the photographer who shot the images for World's Deadliest Fighting Secrets. His name is Bob Sandon and is in retirement in Florida, he is in his 60s and I am waiting on a call back from him today. The shoot was not a buy-out from what I understand.
Sandon is the photographer identified by Doug Dwyer. Sandon shot a lot of photographs for martial artists in the Chicago area back in the 1960s.
I am expecting more discoveries like this to come about this next few months. Patience and good investigative skills will clear up any dispute over intellectual property rights.
Good stuff is happening.
