I have more questions than answers.

Is this the entire photo? If not, the whole photo may be more helpful (even without markings). If so, where was it found? If that info is not available, are there any identifiable marks on the photo (such as photo studio, etc)? Even with all of the above information it is very difficult to identify anyone without a comparable photograph.

I am afraid in its' current state it would be next to impossible to identify this individual with any certainty.
