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

“He will carry Papers and deliver them to such Gentlemen as are pleased to encourage him.”
When Moses Cleveland set about establishing “a Post to ride weekly between Norwich and Boston” in 1774, he initially advertised in the Norwich Packet. He pledged that he “will carry this Paper, and deliver it to such Gentlemen as are pleased to encourage it, with the utmost Regularity.” Soon after, he ran a nearly identical advertisement in the Massachusetts Spy, the newspaper that Isaiah Thomas printed in Boston. Cleveland realized that the success of the venture depended on attracting as many customers as possible at both ends of his route and places on the way.
His notice in the Massachusetts Spy featured a small, but important, variation. It stated that he “will carry this and other papers,” acknowledging that five newspapers were published in Boston at the time, “and the Royal American MAGAZINE.” When I first examined that advertisement, I conjectured that Cleveland had not written that last bit of copy but instead Thomas seized an opportunity to market the new magazine he launched a couple of months earlier. Cleveland’s advertisement gave the magazine more visibility, while the post rider’s service made the magazine accessible to prospective subscribers in Norwich, “WINDHAM, POMFRET, MENDON,” and other towns in Connecticut and Massachusetts.
Cleveland did not advertise in all the Boston newspapers. Perhaps that would have been prohibitively expensive as he sought to raise funds for his venture. Yet he did not confine his advertising to the Massachusetts Spy. Instead, he placed a notice in the Massachusetts Gazette and Boston Post-Boy, again nearly identical. In that one, he declared that he “will carry Papers and deliver them to such Gentlemen as are pleased to encourage him,” making no mention of the Royal American Magazine. This strongly suggests that Thomas did indeed make an editorial intervention in Cleveland’s advertisement, grafting his own marketing efforts onto the newspaper notice purchased by the post rider.
