Sygnały Magazyn (Signals Magazine) was a Polish cultural and social magazine published 1933–1939 in Lwów (Lemberg, today Lviv, Ukraine). It was a leading periodical of the leftist Polish intelligentsia. The journal started as a 12-page monthly and was subsequently published once every two weeks, with editions of up to 32 pages. Sygnały was published in the tabloid format, similar to the New York Times at about 56x40 cm (22x16 inches).
Its editor-in-chief was Karol Kuryluk, and the editorial committee included Tadeusz Banaś, Stanisława Blumenfeld, Halina Górska, Tadeusz Hollender, Anna Kowalska, Andrzej Kurczkowski and Marian Prominski.
Among the literary contributors from Poland figured Erwin Axer, Maria Dąbrowska, Jan Kasprowicz, Stanisław Jerzy Lec, Bruno Schulz, Leopold Staff, Julian Tuwim, Debora Vogel and Józef Wittlin.
International literary contributors included Henri Barbusse, André Malraux, Carl von Ossietzky, Bertrand Russell, Upton Sinclair and Paul Valéry.
The magazine featured reproductions of art work by Alexander Archipenko, Jan Cybis, Xawery Dunikowski, Max Ernst, Henryk Gotlib, Bronisław Linke, Maria Jarema, Bruno Schulz, Henryk Streng and Zygmunt Waliszewski; avant-garde photographs and photomontages by Otto Hahn, Jerzy Janisch, Margit Sielska and Mieczysław Szczuka; and caricatures by K. Baraniecki, F. Kleinmann, Eryk Lipiński and Franciszek Parecki.
Special issues were dedicated to Jewish, Ukrainian and Belarusian culture.
In 1938 an armed ONR (National Radical Camp) gang raided the editorial office and Karol Kuryluk barely escaped alive. In spite of financial hardship and heavy censorship, he published Signals through August 1939.
In September 1939, after the Soviet annexation of Lwów, Kuryluk deposited his Signals archive at the Ossolineum Library (now Stefanyk Library) where it has survived until now.
