In the early days around 1925, the company Kunstkeramik Luzern A.G. had a series of high-quality designs of shapes and decorative motifs at its disposal. Most of these were probably created by Emil Loder. However, it is not clear who added the colour schemes and notes (not in Emil Loder’s handwriting).

Today, the designs are kept in the Kunstkeramik Luzern company archive at the State Archive of Lucerne, PA 1421/PLA 202.
