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

“BURROWS DOWDNEY, Clock and Watch Maker, in Front-street.”
Relatively few advertisements in eighteenth-century newspapers included visual images. Those that did tended to feature stock images that belonged to the printer and could be inserted interchangeably in advertisements from the appropriate genre, such as woodcuts of horses, houses, slaves, and ships. Woodcuts of houses could be used in any real estate notice. Woodcuts depicting runaway slaves could be used in any notice alerting colonists about fugitives that might be in their midst.
Some advertisers, however, did invest in woodcuts to enliven their advertisements, distinguishing them from others that consisted solely of text or that were decorated with generic images readers were accustomed to seeing in the pages of the public prints. Unlike the stock images, these woodcuts belonged to advertisers rather than printers. Even if the image happened to match the contents of other advertisements, such woodcuts appeared only in connection to those who had commissioned them. For instance, clock- and watchmakers regularly advertised in the pages of the Pennsylvania Gazette, yet the woodcut depicting the face of a clock appeared solely in notices placed by Burrows Dowdney. That unique image made his advertisements distinctive and memorable for potential customers, especially since it was sometimes the only image on a page otherwise composed of text (as was the case on the final page of the supplement that accompanied the May 12, 1768, edition of the Pennsylvania Gazette).
Many of the woodcuts commissioned by advertisers dominated the notices in which they appeared, but that was especially true for Dowdney’s advertisement. The image of the clock dial accounted for approximately half of the space his notice occupied on the page. Readers would have been able to identify his occupation and wares at a glance, even if “CLOCKS” and “WATCHES” had not been listed in all capitals in the copy that appeared to the right of the image. Printing technologies of the period did not particularly facilitate including images in advertisements, yet some advertisers still invested both money and energy in experimenting with woodcuts that would set their advertisements apart from others that flooded the pages of eighteenth-century newspapers.
