This was an AoA done on a wooden Triptych, it is based on "St. Sebastian" (fol.179) from the Hours of Henry VIII by Jean Poyet, 1500's, France. The angels are from the same Hours, "Holy Family" (fol.21v). You can't tell from this scan but the angels are on a medium dark purple with metallic gold highlights. I didn't get a scan of the outside of the triptych which has the recipients Arms on it when closed. This is about 7 inches tall (if I remember right).
