Published by Artes Gráficas Federico Álvarez, Toulouse. 15 lithographs on paper with the original album cover. Signed on plate and with the artist's stamped signature in monogram. 14 of them, with the publisher's inscription on plate and with handwritten titles by the artist. It is thought that no more than 30 copies were ever published, of which only 8 are complete, apart from this lot, which was previously unpublished: these are the collections held in Museo de Bellas Artes in Asturias, Museo de San Telmo in San Sebastián, Cau Ferrat in Sitges, Museu Pau Casals in El Vendrell, two in the MNCARS in Madrid, and a pair in private collections. We would like to thank Juan San Nicolás for his invaluable collaboration in cataloguing this lot. Reference literature: Juan San Nicolás, "Darío de Regoyos-I", Barcelona, Diccionari Ràfols, 1990, pp. 124-125; and María Soto Cano, 'Darío de Regoyos y el Álbum Vasco', "Darío de Regoyos en el Museo de Bellas Artes de Asturias", Oviedo, Museo de Bellas Artes de Asturias, 2013, pp. 21-35.
