Very special, possibly museum quality, Royal Copenhagen piece. Darker photos are color enhanced to better show relief characteristics. It has a mermaid emerging from the sea (in relief) and a wonderful fish emerging, in relief, as well. I've never seen another like it. Photos of this piece were sent to Royal Copenhagen and they stated it was an ashtray made between 1900 and 1922. It has a hole for hanging on the top, so I question that it was made as an ashtray, I do not have any other formal information. It is from my mother's estate and she told me once that an appraiser told her it was "museum quality." It is really lovely and I would like to see it go to a "good home" where it will be appreciated. The condition is beautiful as shown in the photos.
