picker
n.— «In flea-market parlance, Erwin is a “picker,” a keen eye who shops on behalf of collectors, museums and other dealers. Though his days are spent navigating jam-packed aisles of furniture and cluttered tables of objets d’art, his nights are savored in a steel-and-glass house in Venice that is surprisingly spare, almost hollow.» —“His cache, minus the clutter” by Janet Eastman Los Angeles Times Nov. 2, 2005.
