Below is a copy of an 1898 Ad for Ivory Soap. I love the claim that "It Floats."
READY FOR BATTLE
An Ivory Soap bath gives a sensation of increased vitality; a longing for activity and for exercise of the faculties; it is a fitting preparation for any battle of life.
Every ingredient of Ivory Soap is sweet, clean and pure. No better materials go into the most expensive toilet soaps, and no soap is so pleasant to use; it has a rich creamy lather that is soothing to the skin as well as cleansing.
