Box number 1: The company, Chocolats J. Klaus S.A., has a mixed Franco-Swiss history typical of major European businesses near the border: Swiss Foundation (1856): The company was originally founded in 1856 by Jacques Klaus, a Swiss chocolatier, with a factory in Le Locle, Switzerland. French Expansion/Entity: The company was a major European entity, and it operated a significant corporate structure in France, notably with shares issued in Paris (e.g., a 1919 share mentions Paris). It is highly likely the "Bonbons Russes" were produced and marketed directly from a French branch or subsidiary to cater to the French-speaking and cosmopolitan market. The second box is Blooker's Cacao (Blooker Cacao Fabriek) • Origin: The Blooker company was a famous Dutch (Netherlands) cocoa and chocolate producer, founded in Amsterdam in 1824. • Product: The product is CACAO (Cocoa) and the text "Daalders" refers to their specific brand or grade of cocoa powder, possibly a reference to the Dutch Thaler or 'daalder' coin, implying value or quality. • History: Blooker's was one of the major cocoa companies in the Netherlands, alongside brands like Van Houten and Droste. The company remained a prominent player in the cocoa market until it ceased to exist as an independent company around 1962. The third is without cup. Company Name: Droste's Cacao & Chocoladefabrieken N.V. 1920-1950 period
