Up for bids is a set of rather rare Blake & Mortimer slide films. The two boxes, which contain no less than 45 films, represent the full story of "Le Secret de l'Espadon" (= Het Geheim van de Zwaardvis" = "The Secret of the Swordfish"). Small signs of use and age, see photos. Le Secret de l'Espadon is E.P. Jacobs' very first Blake & Mortimer adventure. It was first published in Tintin magazine from the very first issue in September 1946. It describes how a far eastern empire takes over the world and the adventures of two Britons as they try to bring about the development of a weapon which will enable them to fight back. Drawing elements from the recent events of World War II as well as the emerging Cold War, the trilogy is set in an alternate reality of the 1950s, in which a Third World War is played out.
