CARRIAGE TRADE: Justice

For the “proud car owner,” Manhattan’s elegant Black, Starr & Gorham last week ran a discreet ad. At prices starting at $30, motorists were offered car keys of gold with religious, scenic or auto insignia “to do justice to [their] shiny possession.” Snappiest model: a miniature Cadillac with movable wheels, ruby tail lights, diamond headlights and a key that retracts into the chassis. Price: $137.
