Butch Cassidy help

[coloradcowboy]

Hi,
I have a question for the experts. I have been researching Butch Cassidy for quite some time. I have come across the original Fort Worth five photo of the wild bunch. The original copy on his face appears to be a blemish on his cheek. I asked two dermatologists that both said the blemish is basal cell carcinoma. I also have seen this cancer on another suspected Butch Cassidy photo. My question is the original photo is the only photo I see the blemish on. Some have said it is a photo defect. Can I get some opinions. Based on the other photo, I believe it is a blemish. Photos were taken 1900 and 1901
Photo on the right is the suspected blemish. Photo left is comparison with other known Butch photo

Are you looking at the actual photo in your hand or is this a scan online? Because it looks to me to be a newton ring from the scanner glass.

Thanks for the reply. It is online not in hand. The photo is 7x9 inches

I was going to say it looks like a water spot around a dust mote on the negative when the print was made.

I only know Butch Cassidy from the movie and in the movie Butch had no carcinomas at all that I could see! Maybe if I watch the movie again and look really closely!!
Not sure if that helps at all?!?! LoL
