I'll tell you what Del-co, do you have any of the standard Billy the Kid books? Ones that have pictures? If so, if you don't mind, pick out a person whose picture you like and tell me who it is and I'll see if I have a picture of that person and I'll post it. Then you can decide for yourself if my pic is legit. I have all of the Regulators except for Charlie Bowdrie, and I may have him. I have all of Sallie Chisum's family except for her uncle Pitzer, who I don't think she liked since he left the South Spring Ranch early...quitting so to speak. I have many pictures of Sallie herself from age two to age seventy-two. I have the Kid, Folliard, Patron, McSween, Brown, Brewer, Scurlock, Wilson, Rudabaugh, Smith (Joe), Jones (not a regulator), probably McNab and Middleton. I've got both Coe cousins and their wives. I even have Matilda Davis, who was the lady who drove Richard Brewer nuts and caused him to leave Wisconsin and become Tunstall's foreman.
I even have Sallie's pictures of the man she married (first husband), and his parents and cousins (He was an only child.). So the question becomes how could I have these little pictures and they were not owned by Sallie. Who else would collect these images, besides Sallie?
Sallie Chisum owned these pictures and she gave them to her favorite niece just before Sallie died. She gave her "papers" to Lily Casey which became the book "My Girlhood Among the Outlaws".
