Saint-Gaudens typically signed his own work (in bronze no less) with a hyphen: his portrait of Jules Bastien-Lepage (1880) for example, or his portrait of William Picknell (1877), his portrait of his son, Homer Saint-Gaudens (1882), his portrait of Charles Beaman (1894), or  his Washington Medal, (1889) inscribed "copyrighted by Augustus Saint-Gaudens". There were exceptions, of course, when he dropped the hyphen, usually when signing with a monogram: his medal of the artist John S. Sargent (1880) is signed "FECE A ST G".
