Trade cards were one of the most prevalent forms of advertising in the U.S. from around 1875 to 1900. They had their origin in England in the 1700s with tradesmen advertising their wares. The advent of lithography in the 1870s made it possible to mass-produce them in color. The Philadelphia 1876 Centennial Exhibition sparked the beginning, as many were passed out at that event.

Marseille soap is typically made from vegetable oils such as olive oil, palm oil or copra (coconut) oil, together with water and seaweed alkaline ash, which acts as a natural foaming agent. The traditional method of making Marseille soap involves a long process of saponification, which is the chemical reaction between oils and an alkali to produce soap. This process can take several weeks or even months, during which the soap mixture is heated, stirred and left to cure. Authentic Marseille soap is typically stamped with its place of origin and can come in various shapes, including rectangular bars or cubes.
