Three Old Men

I'm a big fan of The History Channel's Ancient Aliens.  I love the logic that the show uses.  They will display some mysterious artifact and then say, "While there is no evidence that this thing was used by ancient aliens, there is also no evidence that it wasn't.  Might it then be possible that this was indeed carried to Earth by a flying saucer?"

Well, that sounds reasonable.  And it leads me to wonder about this picture I found in the Historical Society's collection of negatives from Simmons Studio.

While there is no evidence that these three gentlemen were the last surviving members of the Jesse James gang, there is also no evidence that they weren't. Might it then be possible that they indeed came to Warrensburg in the late 1940s to rob the bank, saw the Simmons Studio sign and decided to have their picture taken first?

The fact that there is no mention of a bank robbery in Warrensburg by three old men at that time only suggests that the desire to reform and live an honest life can suddenly hit anyone at any time.

If someone has a better theory about this picture, I'd love to hear it.
