 The painting is signed <unk> <unk> 1832 in capitals at the top left , and <unk> 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 <unk> and richly carved <unk> . Art historians Paul Mitchell and Lynn Roberts note that the design follows an old French tradition of placing austere male portraits within " <unk> carved " frames . The frame closely resembles that of Raphael 's c . 1514 – 15 Portrait of <unk> <unk> , a painting that influenced Ingres , especially in colour and tone .
