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

“ELIZA BRAITHWAITE … is removed from Mrs. Wood’s, to Mrs. M’Cullouch’s.”
Eliza Braithwaite, a milliner originally from London, inserted an advertisement in the Pennsylvania Gazette in October 1769. She informed “the Ladies, and others” that she had changed locations, moving from “Mr. Wood’s, to Mrs. M’Cullouch’s,” still on Market Street but “a few Doors higher up.” She intended to continue pursuing her trade at the new location and called on “those Ladies, who have been kind enough to employ her before she removed” to “continue their Favours.”
Relatively few female entrepreneurs placed advertisements in eighteenth-century newspapers, certainly not in proportion to their presence in the marketplace as shopkeepers and tradeswomen. That made their advertisements notable, then and now. When they did inject themselves into the public prints, some women were bolder than others. Braithwaite took a fairly conservative approach in her advertisement, almost as though she hoped to limit the amount of attention she might receive as a result of making her business so visible. She adopted standard language that appeared in advertisements placed by tailors and milliners throughout the colonies. She did her work with “particular Care.” She charged “the cheapest Rate.” She made hats and other accessories “in the newest and genteelest Taste.” While this could indicate Braithwaite’s familiarity with the conventions of marketing in eighteenth-century America, it might also signal hesitation to distinguish herself too much from her competitors. That she conformed to the expectations of milliners, male and female, may have been the most important appeal Braithwaite wished to advance in her advertisement.
The circumstances that prompted Braithwaite to place a notice in the Pennsylvania Gazette also testified to a conservative approach to advertising. She did address “the Ladies, and others,” but her primary purpose seems to have been maintaining her clientele rather than expanding it. She wanted former customers to know that she had moved so they could find her at her new location and continue employing her. Although Braithwaite’s advertisement exposed her business to much larger audiences, any invitation to new customers was implicit rather than explicit. Did Braithwaite advertise in the Pennsylvania Gazette or any of the other newspapers printed in Philadelphia on other occasions? Whether she promoted her business in the public prints at other times merits further investigation.
