Both sides of a 1910s advertisement for Hudson's Soap, a product developed by Robert Spear Hudson. This folded, diecut card depicts four policemen standing in a row, holding a banner with ten panels proclaiming the virtues of the product, with a further four slogans (such as "Arrest all dirt") on their own backs. Through intense advertising such as this, Hudson's grew from a single shop in 1837 to a company employing more than 1,000 people. The brand was sold by Hudson's son to Lever Brothers (now part of Unilever) in 1908. Today, it is sold under the brand name Rinso.Advertisement: Anonymous; restoration: Adam Cuerden
