The copy of the tintype used in the above comparison has been flipped left to right because the original was a horizontally reversed image, like you see when you look into a mirror.  When Brushy died in 1950 it was not common knowledge that the tintype photo was reversed.  Consequently most people thought the photo showed Billy holding his rifle with his right hand and wearing his pistol on the left side.  Even years after Brushy’s death it was generally not known about the reversed image as attested to by the release of the Paul Newman movie “Left Handed Gun” in 1958.  It wasn’t until much later that most people knew.  Yet by 1950 Brushy had stood for at least two photos where he mimicked the pose he had struck all those years before.  And he got it right!  How would he have known the correct pose when most of his contemporaries did not.
