I might be wrong, but I think this old man is focusing his attention on an upside-down wooden boat in this real photo postcard from long ago.
Who was he? And what is his story? We'll probably never know.
The postcard was never used. The logo on the back (CYKO) is identical to the one that appears on the postcard of "Four women sitting on the ground," which was featured earlier this month. Thus, the postcard dates to sometime between 1904 and the 1920s.
It would certainly be interesting to know who this person — who was likely born before the American Civil War — was, and why someone felt the need to turn this image into a postcard (which was never used).
And was is that in his hand? It's longer than it appears at first glance.
