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

“Those who intend to encourage this Work are requested to send their Names to Peter Valton, Mr. Peter Timothy, or Mr. Robert Wells.”
When it came to publishing newspapers, Peter Timothy, Robert Wells, and Charles Crouch were competitors. All three operated printing shops in Charleston, where Timothy published the South-Carolina Gazette, Wells published the South-Carolina and American General Gazette, and Crouch published the South-Carolina Gazette and Country Journal. This did not, however, preclude their cooperation when it came to other ventures.
In the fall of 1768, Peter Valton circulated a subscription notice that announced his intention to publish “SIX SONATAS For the HARPSICHORD or ORGAN, WITH An Accompanyment for a VIOLIN.” Valton intended for the subscription notice to incite demand. For instance, he highlighted the quality of the paper, promised to print the names of subscribers in recognition of their support for this genteel endeavor, and offered to provide a seventh copy free to anyone who pledged to purchase six. Valton also used the subscription notice to gauge interest in the project. He needed to know if he could attract enough subscribers to make it a viable venture and, if so, how many copies to print without ending up with an unprofitable surplus. To that end, he instructed, “Those who intend to encourage this Work are requested to send their Names to Peter Valton, Mr. Peter Timothy, or Mr. Robert Wells.” When Valton inserted the advertisement in the October 18 edition of the South-Carolina Gazette and Country Journal, its appearance brought together all three of Charleston’s newspaper publishers.
All three stood to profit from the venture, either directly or indirectly. According to Odai Johnson, Wells was the intended printer.[1] Robust sales of the prospective publication would certainly benefit him. Yet all three printers generated revenues by publishing Valton’s subscription notice in their newspapers. Timothy further lent support for the project by collecting the names of subscribers. Promoting a culture of consumption contributed to their livelihoods, even if they were not the producers or purveyors of the printed materials advertised in their newspapers.
