It’s probably not relevant, but I have the equivalent of a baseball trading card that features Belle Starr; I guess they circulated near the end of the Civil War or perhaps shortly after.
And not to be picky (and when someone says that you KNOW they’re being picky — so just forgive me): anyway, prior to 1907 statehood, what is now Oklahoma was divided into 2 parts. The Eastern part of the state was known as Indian Territory; the western part of the state was known as Oklahoma Territory. They were two distinct legal entities. Can’t remember the name of the John Wayne movie, but it involves a young girl who insists on tagging along with him to find her father’s killer. Anyway, they go into Indian Territory to find the killer; I believe she encounters him in Ft Smith Arkansas, which is right on the border.
That was True Grit, and also starred Glen Campbell. Good movie.
