Advert for Wright's Myrrh Tooth Soap reverse
Printer: Calvert Lith Co
Medium: Print on paper
During the late 19th century, many chemists and entrepreneurs made their own toothpastes. There were many varieties and competition was fierce, so advertising on leaflets such as this one was a way of ensuring that as many people as possible recognised your product.
This American advertisement features an endorsement from JA Watling, a professor of clinical surgery in the Dental College at the Michigan State University: "GENTLEMEN - I am satisfied from a careful examination of your Myrrh Tooth Soap, that it contains nothing injurious of the Teeth."
