"Lucien Roisin was a Barcelona-based photographer, originally from Paris. His works are of great importance due to the range of his output--he took photographs all over Spain--and their chronological span, from the beginning of the 20th century, especially the 1920s, to the 1950s. Roisin is mostly known as a postcard publisher and owner of his own business on the Ramblas of Barcelona: La casa de la Postal (The Postcard House). His postcards are the testimony of the dramatic changes the country went through in his lifetime: survival in turbulent times, the disappearance of rural life, the growth of towns and increases in population, industrialization, and tourism. His images memorialized the transformation of landscapes and customs." (Beschreibung Library of Congress, zu: Roisin, Lucien: "Valencia. Market", Barcelona 1928.)
