Loading his shotgun the “marshal” with his foot upon the Wells Fargo lock box, is preparing to board a stagecoach. 

I have wanted to do this man, in a duster, loading a shotgun, for a few years.  The small creative part of my brain has seen him with his double barrel, leaning against a wheel hub, while he loads a pistol, ramming a blunderbuss, or loading a sawed off shotgun with a Winchester in the crook of his arm, before I landed on the lockbox. 

This piece will always be one of my favorites.  As far as I know there was no Jesse Tanner Rankin, but the gun, the lockbox, and the duster are for real.
