Several years ago I purchased this unusual box and it remained on my dresser top for all that time. I was hoping to find out more about it but never did. It is undoubtedly Scandinavian but there are absolutely no hallmarks of any kind.
Also, the metal appears to be bronze. And furthermore, the interior is a mystery. There is a mirror in the top lid (with quite a bit of silvering loss) but the bottom interior gives no hint of having held any typical compact parts and there is no fitted clasp to indicate a pill box. Thus the mystery!
If you look closely at the enamel work you will see that the machine engineered ground is extremely complex as is the use of so many colors of enamel. There are at least 5 colors of enamel and I counted at least 7 different underlying machine engineered patterns in the metalwork - 8 if you count the green area which has no pattern under it but you can say there are 8 different surfaces under the enamel! The outside of the bottom sports an elaborate machine engineered design as well. It's hard to tell from the photo, but the areas at the apexes of the outer scallops that appear black, are pierced areas. The larger circle is elevated from that outer scalloped rim giving it some depth.
All this indicates to me that this was a very special piece executed by a very expert enamel artist such as might have been done by Marius Hammer if done in Norway but possibly done in Denmark or Russia. It does not have a French "vibe" to it.
It measures 1 3/4" in diameter and 1/2" high.
