James Reynolds Art 1960 Portrait Sketch

I purchased this drawing from the daughter of the subject.  It appears to be the kind of portrait done by a street vendor or at a fair booth, but it is very well done.  I have been trying to find out more about James Reynolds and whether he ever worked at something like that (I know he didn't start doing western paintings until later).

Any information on the value would be very much appreciated, and I would consider selling it.
