Tintypes are reverse images. It’s this that led people to believe the “Kid” was left handed. He wasn’t.
I have a picture on my computer that was taken about 10 years ago, it is of my niece and me sitting on a couch with my arm around her. It's one that I scanned and put on my computer, not digital direct down load. It was on my computer for a few years before I noticed that I had my left arm around her and my left hand with all its fingers showing.
It freaked me out because my middle finger, left hand, had been amputated for years before that picture was taken, yet there it was in all its glory magically back on my left hand.
I had to dig to find the original hard copy photo but when I found it my right arm and hand were around her shoulders. My scanner had reversed the image.
A clue that I missed entirely, was that the supposed left hand didn't have a wedding band on it that I always wore on the left ring finger.
