I am not sure what trick the magician performs, but the piece looks to be in fantastic shape. The seller writes that this is an automaton by Adolphe Mueller of Germany from circa 1895. It is in working condition. The piece stands 80cm high.
Given the cone in the magician's hand, I would assume that an item on the the table either disappears or is transformed into another item altogether.
I am impressed with the clothing and fabrics on this piece. This must have been in a a carefully maintained collection.
