Grandbury is a town (small city now) about 30 miles southwest of Fort Worth, Texas. My own grandmother grew up there. I have not been able to research this photograph and the next one. The man is identified as Tom Mullins who was a lawman in Grandbury. He wears a cartridge belt with a holstered Colt in it. I would say the image is after 1900. Other identifications indicate that he and his brother Sam were killed by a man named Ed Waldry. That is all I know about this Texas mystery. The photograoh was taken by Mouzon & Co., Grandbury, Texas.
