Etched Gold Cups. Circa 1870. Set of four finely made etched golden cups with the intitals ?D/A? in central medallions in the side of each vessel, and incorporating shallow saddles and a traditional tapered design for the ancient conjuring feat of the Cups and Balls. The fourth cup outfitted with a series of twenty four sharp spikes, allowing the performer to secretly pick up a cork ball placed underneath it. Height 3 ??, mouth diameter 3 ??. An outstanding early set of cups and the first we have encountered in this form. See Salon de Magie, page 90.
