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

“She continues to sell … the genuine flour of mustard.”
Mary Crathorne advertised the mustard and chocolate she “manufactured” at “the Globe mill on Germantown road” in more than one newspaper published in Philadelphia in February 1768. She inserted one notice in the Pennsylvania Gazette on February 11 and another in the Pennsylvania Chronicle on February 15. Although they featured (mostly) the same copy, the visual aspects of the tow advertisements distinguished one from the other.
A headline consisting of her name, “Mary Crathorne,” introduced the advertisement in the Chronicle. Such design was consistent with that in other advertisements placed by purveyors of goods and services, including Robert Bass and John Lownes. It added readers in identifying the advertisement, but did not call special attention to it. In contrast, her advertisement in the Gazette featured a woodcut depicting a seal for her company flanked by a bottle of mustard on one side and a pound of chocolate on the other. It was the only advertisement in that issue of the Gazette (including the two-page supplement devoted entirely to advertising) that incorporated a visual image, distinguishing it from all others. On the other hand, Crathorne’s advertisement in the Chronicle ran on the same page as four advertisements that included woodcuts (a house, a ship, a male runaway servant, and a female runaway servant). In addition to those stock images that belonged to the printer, elsewhere in the issue Howard and Bartram’s advertisement featured a woodcut of dog with its head in an overturned bucket. The “Copper-Smiths from London” ran a shop at “the sign of the Dog and Golden Kettle, in Second-Street.” They effectively deployed the visual image in multiple media, the newspaper advertisement and the shop sign, to create a brand for their business.
Crathorne attempted something similar with her own woodcut in the Gazette, noting that “All the mustard put up in bottles, has the above stamp pasted on the bottles, and also the paper round each pound of chocolate has the said stamp thereon.” She had to revise the copy, however, for inclusion in the Chronicle without the woodcut. “All the mustard put up in bottle has a stamp” (rather than “the above stamp”) “pasted on the bottles, and also the paper round each pound of chocolate has the same stamp thereon.”
Apparently Mary Crathorne (or her late husband who previously ran the business) had commissioned only one woodcut of this trademark image. That made it impossible to publish advertisements featuring the same image in multiple newspapers simultaneously. The aspect that most distinguished her advertisement in the Gazette was completely missing in the Chronicle, where other advertisers treated readers to a series of woodcuts that dressed up their notices. Crathorne engaged in innovative marketing efforts by associating a specific image with her products to distinguish them from the competition, but she did not consistently advance that campaign by inserting the image in all of her advertisements that appeared in print. She recognized that branding could be useful in selling her wares, but she did not apply the strategy to full effect. That required further experimentation by other advertisers.
