A finely turned impossible object/puzzle in the form of a polished wooden napkin ring with an outer ring encircling it - but with no way to remove the outer ring. Likely turned out of a single piece of wood, circa 1880, and in fine condition. An antique conversation piece from the era of Hoffmann's famous book, Puzzles old and New, and exquisitely finished. The perfect vintage addition to your puzzle collection or cabinet of curiosities.
