The Compagnie Financière belge des Pétroles (the Belgian Petroleum Finance Company) -- later known as simply "Fina" — was founded in the Twenties. After World War II, Fina expanded outside its original home base into other areas of Europe, as well as Africa and North America. The company eventually was to retrench its operations in the Eighties. This is an early 1960s issue of Fina's home country of Belgium.
This map of Germany was issued in 1961 and though it's titled as a Tankstellenverzeichnis (service station directory), it's an ordinary road map with a station listing on the rear. For some reason, Fina's logo in Germany had two notched edges, unlike other countries in which Fina operated.
