The REAL Clark Kent

From Sean Clement of Diverging Comics:
I was going through one of the books that I got from the Library and this photo (link posted above) struck my eye. It features a man who was apparently, or might of been, the basis for Superman's alter ego. I thought it was extremely interesting and had to share it with you guys. The book I got "Superman: The Complete History" is very fascinating. If you get a chance to read it then do so.
