This Art Nouveau jewelry box is a bit unusual in that the finish is copper rather than the usual gold or silver finish. The style has the typical curves and florals of the Art Nouveau period. The inside has a satin lining in very good condition. It may be original, but I cannot be certain. It certainly fits with the time. The bottom is marked Trade Mark J.B. signifies the Best. 606. This box is small, measuring 3 1/2" x 2" x 2 1/2". Very good condition. I have left it in its original condition. It could be cleaned if a shiny copper lustre is desired.
