The Société Parisienne d'Édition (S.P.É. or SPÉ), originally known as Offenstadt Frères then Publications Offenstadt, was a French publishing house founded by the Offenstadt brothers towards the end of the 19th century. They adopted the name "Société parisienne d'édition" just after the end of the First World War. The five Offenstadt brothers – Charles, Georges, Maurice, Nathan and Villefranche – had a wide range of publications within their portfolio, exploiting technical advances in low-cost colour lithography. They are best known for publishing popular periodicals aimed at the youth market, such as L'Épatant, L'Intrépide and L'Illustré; and comics, often featuring larger than life characters like Les Pieds nickelés, L'Espiègle Lili and Bibi Fricotin. They also published magazines aimed at adult audiences, providing a platform for emerging and sometimes controversial writers and artists – such as Maurice de Vlaminck and André Derain. They were among the first to publish (in Sciences et Voyages) Jean Vieuchange's bestselling account of the epic journey to Smara, made by Jean's brother, Michel Vieuchange in 1931.
