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

“Once more!”
In the August 26, 1769, edition of the Providence Gazette, Knight Dexter and Samuel Nightingale, Jr., both placed advertisements calling on those who owed them money to settle accounts or risk being sued. When it came to attracting the attention of readers, however, Dexter deployed much more effective typography that included a striking headline.
Compare the two advertisements, staring with the standard format adopted by Nightingale. “ALL Persons indebted to SAMUEL NIGHTINGALE, jun. by Book, Note, &c. are once more earnestly intreated to make immediate Payment.” The advertisement continued from there with the threat of legal action and a shorter paragraph that promoted the “large Assortment of European and West-India GOODS” in stock at Nightingale’s shop. The shopkeeper’s name and “GOODS” were the only words that appeared in all capitals. None of the text in the advertisement ran in a larger font. Visually, little distinguished it from other advertisements or other content in the issue.
On the other hand, Dexter’s advertisement opened with a headline that demanded attention: “Once more!” The font for the headline was even larger than that used for “PROVIDENCE GAZETTE” in the masthead on the front page. Elsewhere in the issue, only prolific advertisers Joseph Russell and William Russell used a font notable for being larger than anything else on the page; their names ran in font the same size as “PROVIDENCE GAZETTE” in the masthead. “Once more!” appeared in the largest font by far on the third page and the second page that faced it, making it difficult to miss. Such unique typography likely incited curiosity and prompted readers to investigate further and find out more about the advertisement.
Although unusual, the typography was not completely unique. In December 1768, Joseph Olney, Jr., and Jonathan Arnold, executors of the estate of Joseph Smith, ran an advertisement calling on creditors to settle their debts and advising the community of an estate auction. The advertisement featured the “Once more!” headline in oversized font. It ran in the Providence Gazette. Perhaps Dexter, who advertised frequently in that newspaper, remembered that advertisement and incorporated its distinctive feature into his own advertising several months later. Alternately, perhaps the printer or compositor recommended the striking device to Dexter when he expressed concern about attracting as much attention to the advertisement as possible. Either way, this innovation that originated in the Providence Gazette did not disappear after its first use. It reappeared within a year, heralding a practice that became common in newspaper advertising in the nineteenth century.
