Night of the Casual Killer. Someone pointed this out to me lately. Check out the guy on the left in all three pics! Yes, sunglasses were standard equipment for western dudes in the 1870’s, right?
In the first pic, while everyone else was looking off in the same direction, watching Jim West walk toward them, Mr Shades and the guy beside him were staring straight at the camera. Then when Jim arrived and Mason (guy on right) started picking on him, Shades suddenly realizes his glasses are in the shot and quickly yanks them off and gets them out of sight.
