Vintage 1970s DeMott brass and onyx sailboat sculpture

Straight from the 1970s Vintage DeMott signed Brass sailboat sculpture Onyx base with green felt I’m have not cleaned this at all because I wanted the aged patina to remain Also there is a flaw in the brass weld as seen in the last two pics. The brass “rope” will stay in the correct position, but it will move too. About 15.5” x 5” John and his brother Don DeMott were discovered by Macy’s Department Store in the 1970’s.
