After the 37th auction, Ketterer closes the Stuttgarter Kunstkabinett and puts an end to his activity as an auctioneer. He also moves away from Germany and settles in Campione d’Italia, by Lake Lugano, where he later opens the R. N. Ketterer gallery. That year the baron starts lending Expressionist works to international exhibitions.
Ketterer hosts the Moderne Kunst I exhibition at his new gallery. The baron visits the show and acquires canvases by Feininger and Kirchner. To establish the price of each picture – as Ketterer later recounted – they would each write down a sum on separate pieces of paper. Although it was ultimately the gallery owner’s price that counted, the baron’s was usually higher.
