As indicated by the caption, this image shows one of several variations of sculptor Jean-Leon Gerome's "Cornith" that is not likely to be the same one that Clarence Mackay brought home from the 1904 World's Fair.
The caption accompanying this photograph reads as follows:
One of several variations, this version of French painter and sculptor Jean-Leon Gerome's 'Cornith,' is owned by the Getty Museum. But lacking a jewel-mounted bracelet, it is not likely to be the sane one Clarence Mackay brought home from the 1904 World's Fair.
Obviously, the word "sane" in the caption should have been "same" instead.
A photograph published in the November 1, 1908 edition of the New York Tribune of the "Tinted Venus" sculpture by sculptor Jean-Leon Gerome shows the version that Clarence Mackay brought home from the 1904 World's Fair and placed in his glass piazza. That image has been placed here in the Library.
