NEW YORK — Three small, silver spoons elegantly engraved with the words ‘‘Waldorf Astoria’’ have come full circle: Stolen eight decades ago by an employee of the hotel, they passed through two Brooklyn homes and another three in New Jersey.

Then, earlier this month, Brigid Brown packed them up, took them back through the chandeliered foyer of the elegant hotel and plunked them down on a table — as part of a Waldorf amnesty program that seeks the return of pilfered property, no questions asked.
