Two photos from an Ebay seller in Danville, Virginia.

Both are from the McManus Brothers studio. The top photo is a man posing with his dog. The man holds a book in one hand.

Unidentified man with dog.

The second photo has on its back: "Aunt Jule This is W. N. Kelley Nellies' Husband.

Walter Nathaniel Kelley has an entry on the Findagrave website. He was born in 1866 and died in 1938. There is a different photo of him posted on that website, and my photo appears to be a younger version (he had gotten rid of the mustache, changed his hair style, and gotten plump by 1903). He was married first to Nellie L. Van Lieu, who died in 1908. 

Walter Nathaniel Kelley, circa 1890.
