This image shows the front page of the New-York Tribune Illustrated Supplement dated Sunday, July 27, 1902 with the following headline in all capital letters: THE NEW HEAD OF THE MACKAY FAMILY, CLARENCE H., COMBINES GOOD BUSINESS ABILITY WITH A LOVE OF HORSES. The page features several photographs of Clarence Hungerford Mackay (US1797) and five of his horses. It is not accompanied by a caption but we know that the year is 1902 given the date of the newspaper.
See Harbor Hill, Clarence Hungerford Mackay's Mansion.
