What was advertised in a revolutionary American newspaper 250 years ago this week?

“He presumes every Friend to America, both in Town and Country, will encourage him occasionally.”
When Cornelius Cooper, a “BRUSH-MAKER, from Philadelphia,” relocated to Providence, he ran an advertisement in the October 7, 1775, edition of the Providence Gazette to introduce himself to his new neighbors and prospective customers. The newcomer announced that he “makes and sells, Wholesale and Retail, Sweeping, Hearth, Cloaths, Shoe and Buckle Brushes, and every other Article in the Brush Way.”
Realizing that he was unknown to the residents of Providence, Cooper realized that he might increase sales by giving them sound reasons to purchase his brushes, either to use themselves or to stock in their shops to sell to others. “As our own Fabrications, of every Kind, hold forth their Utility, in a most conspicuous Manner,” the brushmaker declared, “he presumes every Friend to America, both in Town and Country, will encourage him occasionally.” Cooper did not need to rehearse current events for readers to understand his meaning. They knew that the siege of Boston continued, following the battles at Lexington and Concord in April and the Battle of Bunker Hill in June. They also knew that the Continental Association, a nonimportation agreement devised by the First Continental Congress, went into effect on December 1, 1774, in response to the Coercive Acts. Colonizers sought to use commerce, especially their choices about consumption, as political leverage to convince Parliament to repeal the Boston Port Bill, the Massachusetts Government Act, and other legislation. The Continental Association also called on colonizers to encourage domestic manufactures or the production of goods in the colonies as replacements or substitutes for imported ones. Cooper did his part in making brushes. Now “every Friend to America” needed to do their part by supporting his enterprise.
Making purchases was not the only way they could do so. In a nota bene, Cooper requested “that People will be careful to save their Hogs Bristles, for which he will give a good Price in Cash.” Consuming goods made in the colonies was important, but colonizers could also participate in the production of those goods by collecting materials, delivering them to Cooper, and earning some cash for their efforts. The brushmaker also noted that he sought an apprentice, “a discreet, active Lad, about 14 Years of Age.” He would pass along knowledge of his trade and make help the next generation contribute to the local economy. Readers understood the inspiration and political ramifications without Cooper going into detail in his advertisement. He presented them with a patriotic obligation and encouraged them to do their civic duty in the marketplace.
