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

“Most Kinds of BLANKS to be sold at the Printing-Office.”
Eighteenth-century printers often inserted advertisements for their own wares and services in the newspapers they published. They hoped to generate additional revenues, but they may have also strategically placed their own advertisements as a means of generating content that would fill space. Unlike other advertisers who usually purchased “squares” of advertising, thus paying by the length of the advertisement, printers who promoted their own enterprises did not have to factor the length of their advertisements into their calculations. That sometimes resulted in lengthy advertisements or multiple notices in a single issue.
In this case, however, printer James Johnston inserted a very brief advertisement, a single line announcing, “Most Kinds of BLANKS to be sold at the Printing-Office.” (By blanks, Johnston meant a variety of forms, including indentures.) The advertisement appeared at the bottom of the second and final column on the last page of the newspaper, nestled right above the colophon. Johnston needed one more line of text to complete the column. This one had the added benefit of drawing attention to one of the services he provided.

Like many other eighteenth-century printers, Johnston also used the colophon (the space devoted to publication information, including printer and location, at the end of the newspaper) to promote both the newspaper and other parts of his business. In addition to noting that the Georgia Gazette was “Printed by JAMES JOHNSTON, at the Printing-Office in Broughton-Street” in Savannah, it also announced that he sold subscriptions and advertisements. Furthermore, he did job printing (like the blanks) “at the shortest Notice,” including handbills and other forms of advertising (such as broadsides, trade cards, or circular letters).
Throughout the eighteenth century, Johnston and other printers creatively shaped newspaper colophons to do more than provide basic publication information. They use them to promote other services available in their printing shops.
