It is very funny that you suggest Kurt Vonnegut, for reasons I cannot explain...
But it's not him. Vonnegut was born in 1922: does it look like picture taken around 1925?
Also, when I said the indian motives of the chairs could be a clue about his birthplace, I was not suggesting Indiana, a state whose name does refer to "indians" but where they were few indians left at the time of his birth. I am not aware of other relations of Vonnegut with native americans, but I may be wrong.
I was not suggesting Oklahoma either, so no need to google "Tony Hillerman".
