Patent medicine ephemera

Accession: 2022-228

Patent medicines, also known as proprietary medicines, are non-prescription medicinal remedies that are trademarked and whose ingredients have been granted protection for exclusivity. The term "patent medicine" has become particularly associated with drug compounds manufactured during the eighteenth and nineteenth centuries. In actuality, the patent medicine recipes were not officially patented. Patent medicine promoters pioneered many advertising and sales techniques; this small collection primarily features trade cards and almanacs.

Dates: 1877-1937
