Signed art piece with copper encased in lucite acrylic. The form of the copper reminds me of coral. The cube measures about 3-3/4" squared. This was a thrift find that upon cleaning I discovered was also signed. The base has a signature that looks like Slocum 1/1. It is possible this piece was intended as part of a periodic table of elements display. The cube does have a bit of superficial scratches. The scratches could potentially be buffed out. The scratches should be visible in some of the photos.
