The Princeton Historical Society identifies this as Moses Taylor Pyne and another man, in the gardens at Drumthwacket, 354 Stockton Street, Princeton, New Jersey. Moses Taylor Pyne (1855–1921) bought Drumthwacket in 1893 and worked with architect Raleigh Gildersleeve to renovate and expand the house and gardens.

Drumthwacket was built in 1835. The house was the private residence of three owners, Charles Smith Olden, Moses Taylor Pyne, and Abram Spanel, before being purchased by the State of New Jersey in 1966. Intended for use as the official residence of the governor, it was not until 1981 that funds were raised by the New Jersey Historical Society to begin to accomplish the task.
