This is the only enamel of this type I've had marked BOUCHER rather than the earlier MB. It's just gorgeous and certainly in the earlier style! The enamel ranges from lavendar through purple and mauve to a yellow eye just under the central champagne pearl. It's 1.75" tall by 2" wide, set in rhodium. Marked BOUCHER but without the later design numbers. NEAR-MINT condition and just elegant.
