How were historical flasks used in American political campaigns during the 1800s?

Historical flasks, produced in the United States between 1815 and 1870, were utilized in American political campaigns during the 1800s as a form of propaganda. These flasks often featured portraits of presidential candidates, as well as emblems and slogans associated with their campaigns. For instance, William Henry Harrison was depicted on flasks in connection with his 1840 "Log Cabin and Hard Cider" campaign. Thomas W. Dyott, a patent-medicine vendor and bottle manufacturer, was among the notable figures whose portraits appeared on these historical flasks. The production of these flasks provided an outlet for manufacturers like Dyott, who purchased the Kensington Glass Works in 1833 and employed 400 workers.12
