Dulac was commissioned by Her Serene Highness, Princess Alice of Monaco to paint her five-year-old goddaughter, Vivian St George in 1917. Who knows whatever happened to Vivian (who would be 99 if she were still alive today), but she is forever five in a near fantasy setting appropriate to Dulac.
But not such fantasy, as those are Vivian's pet rabbits. Dulac sketched the rabbits from life in a series of spontaneous brush and ink drawings, some shown below.
