This cowboy is steadying his aim at us by using the saddle of his grazing horse.
The vintage unsent postcard is brightly colored with no maker identified on it. The back, which is unstamped and not postmarked, rambles, "A Typical Cowboy--Life on ranches has changed so much in the past few years that we seldom see one of the original cow punchers. The same types drift to the west however, and these men are known for their big heartedness and free way of living."
It is in fairly good condition (check all photos closely) with a tiny crease in the upper left corner and what appears to be some erased writing on the back. It measures 3.5" by 5.5".
