Imagination and creativity have always been sought-after qualities in competing for customers. However, it was not until the large-scale production of commodities in the wake of the industrial revolution that advertising became all-important. This publication focuses on enamelled signs with product advertising. They began to appear in large numbers around the end of the 19th century and reached their heyday between 1900 and the late 1930s. Weatherresistant and using bright colours, they advertised industry products, especially the new branded goods. Several well-known artist studios, but also designs created by anonymous hands, shaped the image of the flourishing advertising industry. Gert and Sonja Wunderlich from Leipzig started collecting the colourful enamel signs early on. A small selection of their extensive collection has been put together in this volume. The history and the stories associated with this collection, like the media's artistic quality, have lost none of their fascination today.
