In 1939, a woman came to Verdura's showroom selling a set of 18th Century painted ivory chessman from India. He bought all of them and transformed them into exquisite bejeweled brooches. Inspired by the Dinglingers' work in the Dresden Green Vaults, the elaborate pieces sold out. Some of the brooches were accompanied by a stand to be displayed.
