Important Copy of A.C. nº 6 (1933), from the Library of Karel Hannauer, with Material on the Arosa Collective House

G.A.T.E.P.A.C. – A. C. Documentos de actividad contemporánea. Portada nº 6, Año II (1933) Barcelona: G.A.T.E.P.A.C., 1933. 4to, original wrappers, 54 pp. with large advertising appendix. Single issue of the seminal Spanish modernist journal, from the estate of the Czech Functionalist architect Karel Hannauer, with his ownership inscription (“my own copy”) in blue pencil on the front page, along with his name. This issue features Hannauer’s groundbreaking Dům Arosa (Casa Arosa, Prague) on pp. 34–35, illustrated with photographs by Josef Sudek (uncredited); accompanied by typed notes on the building laid in. Published between 1931 and 1937, A.C. served as the principal organ of G.A.T.E.P.A.C. (Grupo de Arquitectos y Técnicos Españoles para el Progreso de la Arquitectura Contemporánea), the key vehicle for the introduction of rationalist architecture in Spain during the Second Republic. This celebrated issue is devoted to the sanitation crisis and urban conditions of Barcelona’s Barrio Chino (Distrito V), combining statistical graphics with a powerful photographic report by Margaret Michaelis documenting poverty and urban degradation. Also includes contributions reflecting the magazine’s international outlook: works by Hans Arp and Sophie Taeuber-Arp; articles on skyscraper development, American architectural models, and collective housing inspired by Le Corbusier. An outstanding and socially engaged issue of one of Europe’s most important avant-garde architectural journals, further distinguished by its association with Hannauer, whose Arosa building (Prague, 1931) represents one of the earliest realizations of collective housing in Czechoslovakia.
