Who is that cowboy at the LongHorn bar?

Before Clint Eastwood, there was William S. Hart |
Fat City reader Vernon Justice from Kansas City, Kansas, wrote in with an interesting question about a cowboy he’d seen in the bar at the LongHorn Steakhouse in Wyandotte County’s Legends complex. Not a real cowboy, but a vintage photograph.
“I was intrigued by a picture near the bar. The photograph was an old still from some silent movie. The actor in the picture wore a ten-gallon hat, a six shooter, boots and spurs. He is standing at the bar, facing the camera. I do not recognize the silent movie actor, but the picture is signed Witzel. Can you tell me more?”
Actually, yes I can.
