- Lot Description
The Change Box. Lake Forest, IL: John McKinven, ca. 1995. A colored bead is dropped into a turned wooden vase. When poured out again, the bead has changed color. This can be repeated four times, the bead changing color each time. Turned wooden vase height 7 ½”. Hallmarked. Unusual dark finish (likely turned in walnut).
McKinven modeled this vase after a description of Une Boite a Transformations published in St. J. De L’Escap’s Les Secrets de la Prestidigitation, published in 1913. He manufactured perhaps fewer than 12 units.
