What was advertised in a colonial American newspaper 250 years ago today?

“John M’Lane stop’d last Wednesday Night a Large Silver Spoon.”
Watchmaker John McLane advertised his services in the Boston Post-Boy for several weeks in December 1767. He relied on two marketing strategies to attract potential clients, one commonly used by artisans and the other a clever innovation that testified to his character in addition to his credentials.
McLane opened his advertisement with a recitation of his training to assure customers that he was qualified to work as a watchmaker. He had completed an apprenticeship, having “serv’d his Time in Dublin to one of the best Finishers there.” On its own, this might have impressed prospective clients, but McLane also reported that he received additional training when he “work’d in London for improvement.” Artisans who migrated across the Atlantic frequently asserted their connections to the largest and most cosmopolitan cities in the empire, often providing details about their previous training and work.
McLane’s second strategy, however, deviated from colonial artisans’ usual marketing practices. He appended a nota bene that reported he had “stop’d last Wednesday Night a large Silver Spoon.” In other words, a man that McLane deemed untrustworthy had attempted to sell him a spoon, but the watchmaker suspected stolen goods. He confiscated the spoon and advertised descriptions of both the spoon and the man who attempted to sell it to him. The owner, upon recognizing the monogram or “Marks of the Spoon,” could contact McLane to have it returned.
When he “stop’d” the silver spoon, McLane prevented it from circulating in an informal economy or black market, an alternative means for many colonists to participate in the consumer revolution. Less scrupulous artisans would have purchased it at a bargain price and not questioned how the stranger who presented the spoon had acquired it. By taking this action, McLane demonstrated his character to potential customers in a manner they might remember longer than they would recall his training in Dublin and additional experience in London. Not only was he skilled, he was also trustworthy.
