I have had this photograph in my collection for several years. It comes from my mother-in-law's side of the family and is a graduation photo. (See the scroll in the young man's left hand and the books under his right.)
Unfortunately, no one knows who this young man is, though it's believed to be a relative of my grandmother-in-law (Rose Levitt Goldstein).
Kaufman Studio, 287 E. Houston St., New York is the photographer. New York City Directories at Fold3.com has Sol Kaufman working at that address from 1908 to 1918, and likely longer, but I only checked a few years.
