Child & Child - An Art Nouveau gold, silver, enamel and sapphire brooch, circa 1900. Signed. This extraordinary jewel and the smaller verson are based on the Egyptian prophylactic symbol known as the 'winged globe'. This particular example is remarkable in that the wings are hinged and can be pitched at any angle to suit the owner's mood. Source: Charlotte Gere and Geoffrey C.
