Gas burner for lighting with the flame directed downward into a luminous mantle. The advantage of this device is to provide light without the shadow of the burner. This poster has two variants: one highlights the product brand: Mars, the other the name of its manufacturer: Société des Verreries pour l’Éclairage (S.V.E.).
The activity of the Dupont d'Isigny company began with the production and trade of Isigny butter. From 1894 onwards, in La Cambe in the Calvados department, it became a dairy specializing in the production of milk, butter, and cheese. In 1932, the activity diversified with the production of biscuits and the famous caramels.
Today the company has stopped producing biscuits. It is now mainly dedicated to the production of its famous caramels.
