Photograph of a boy identified on the reverse as Harry Burnham. The photograph was taken at the Janson studio of Beverly, Massachusetts.
Harry might have written his name himself.
Harry Burnham or Henry Burnham was a common name in Essex County, Massachusetts, including those whose first names were Harry or Henry and those with the middle name Harry or Henry.
One possible prospect is the Harry Burnham who was born 30 July 1900 at Beverly, Massachusetts, the son of Harry Burnham and Esther E. (Wentworth) Burnham, who were born in Ipswich, Massachusetts, and Nova Scotia, respectively.
Another possibility is Harry Carlton Burnham, born 23 January 1884 at Beverly, Massachusetts, son of A. Perley Burnham and Addie M. Foster) Burnham, both Beverly natives.
And there are others.
