This image is not accompanied by a caption but we know that the year is 1902 since it is a crop from another image showing Katherine Alexandra Duer Mackay (US1797spouse1) with one of the Mackays' automobiles. The gentleman appearing in that image appears to a chauffeur who the Mackays retained.
There is no caption accompanying this image. The caption accompanying that other image reads:
1902
See Harbor Hill, Clarence Hungerford Mackay's Mansion.
