- Porcelain enamel on steel sign — a durable type of advertising collectible made by baking colored powdered glass onto steel at high heat.
- The glossy finish and layered colors (in this case, white, navy blue, and turquoise) are classic for mid-20th century signage.
- The slogan “Absolutely Pure” and the styling (block lettering with decorative swans in repetition) dates the sign to the 1940s–1950s.
- This is consistent with Swan Soap’s peak marketing push in the World War II and post-war era.
- Given the wear and rusting, it shows authentic age and is not a reproduction.
- The row of swans along the top and the center swan with a banner (“White Floating”) are classic motifs from Swan Soap’s branding.
- The bold contrasting blue/white palette was chosen for legibility and cleanliness — directly linking to the purity message.
About Swan Soap
Swan Soap was introduced in 1941 by Lever Brothers (today part of Unilever). It was marketed as a mild, floating, pure soap, similar to Procter & Gamble’s Ivory Soap, but positioned as more luxurious.
The advertising emphasized its “absolutely pure” quality and the fact that it floated in water, which was a unique and memorable selling point. Swan Soap was discontinued in the 1970s, but during the 1940s–1950s it was heavily advertised on radio and TV, even sponsoring shows.
This particular porcelain enamel sign would have hung outside a general store, drugstore, or market to promote the brand.
