Ludwig van Beethoven was the first enamel box produced for the Classical Composer series by Halcyon Days. This limited edition box was issued in 1970 with an edition size of 1000, and was especially made for sale by Cartier of New York. The Beethoven box was the first of five classical composer boxes issued in this series.
