Enamel is one of my favorite things, and Allan Heywood of Australia was one of my favorite artists. He died a few years ago and it is increasingly difficult to find his work outside of fine galleries. This butterfly is akin to a French paillon in enamel--just bigger. The enamel is mesmerizing. The piece is on copper with a tested silver pin-back. It measures 1 and 7/8 by 1 and 5/8 inches, and is in excellent condition.
