Wooden trash can clad in decorative copper panels embossed with fairytale figures. For more than 30 years (the last 20 in her eponymous LA shop) Liz Gordon has spread the gospel of hardware. Interior designers, homeowners, and set decorators have all become converts. The first step into the shop is overwhelming: More than a million pieces of vintage and contemporary hardware, lighting, and accessories beckon. In the extraordinary mix: 19th-century doorknobs, Murano-glass chandeliers, midcentury flatware, leather cabinet hardware, and art in the gallery upstairs.
