I am certainly open to the possibility because Backes being wrong is not a hard sell to me. But, there is this other image of Beck on the right which is from a Dallas newspaper. They claimed in it that that was Beck.
So, Denis made this collage below, and I added the picture of Beck from the newspaper.
So, this all Denis' work except for the image of Beck from the newspaper. But, as I look at it, the newspaper image of Beck seems to match the image on the far right that Denis is calling Pinkston.
That looks to be a pretty damn good match to me. Do you see how both have a long, slender face? So, I'm thinking that, in this case, perhaps Denis has it wrong, that he has them reversed, and Backes had it right. I have lightened the image on the left.
Wait, was he smoking a pipe? He appears to be smoking something. So, in both images, they are both smoking, and they appear to be the same guy. And they are both wearing tall hats.
But, wait a second. Nat Pinkston lived 96 years. Smokers don't usually last that long. And you can see in the image below that he didn't have a long face.
So Denis, I gotta tell you, pal, I think you're full o' shit on this one. I think you got bettered by Backes, and that's pretty sad. I hope it doesn't happen to you too often.
