Passe Passe Ball Vases. New York: Martinka & Co., ca. 1890. Magnificent set of lathe-turned boxwood vases, each containing a 2 ?? diameter wooden ball, one red, the other black. When covered and uncovered with the lids, the balls change places, back-and-fort. Each vase 9? high. Minor chips and wear, including chips to the rim of one shell, but in good working order. An outstanding oversize example of this classic effect. Each vase is marked with the inventory number of the Circus Museum of Sarasota, ?CMS 243,? underneath its base.
