 The painting is signed J.Ingres Pinxit 1832 in capitals at the top left , and L.F. Bertin , also in capitals , at the upper right . The frame is the original , and thought to have been designed by Ingres himself . It shows animals around a sinuous and richly carved grapevine . Art historians Paul Mitchell and Lynn Roberts note that the design follows an old French tradition of placing austere male portraits within " exuberantly carved " frames . The frame closely resembles that of Raphael 's c . 1514 – 15 Portrait of Baldassare Castiglione , a painting that influenced Ingres , especially in colour and tone .
