Annemarie Davidson is an enamel artist in Sierra Madre, California, who has been making exquisite items since the 1940s.  Her work is highly collectible, especially the vintage pieces, and is still being produced today by the octogenarian.  Here is a teak and enamel-over-copper box with a teak knob on the lid.  The box is signed by the artist.  Approximately 5" tall and 5" in diameter.
