"Portrait of a Child" by Camille Corot (1835) at the Metropolitan Museum of Art, New York - From the curators' comments: "This work was once thought to be a portrait of the painter Rosa Bonheur (1822–1899) as a child, but it seems to represent a boy. Corot's portraits were limited to friends and members of his family, but thus far the figure remains unidentified."
Édouard Vuillard (French, 1868–1940). Self-Portrait with Waroquy, 1889. The Metropolitan Museum of Art, New York. Gift of Alex M. Lewyt, 1955 (55.173) | In his sober, high-collared garment, the pensive twenty-three year old Vuillard might be taken for a civil servant or a clergyman. Only the palette and paintbrushes in his right hand identify him as a painter.
