The illustrator was Jenaro Pérez Villaamil in collaboration with Patricio de la Escosura, who was responsible for the text.

The work was created by a collaboration of writer Patricio de la Escosura, with lithographer Louis-Julien Jacottet (1806–1880), and the artist Jenaro Pérez Villaamil who also acted as editor.

Other artists also contributed including his brother Juan, Valentín Carderera, José Domínguez Bécquer, and Cecilio Pizarro.

The illustrations echoed Pérez Villamil's style which celebrated a romantic medieval aspect.

Despite the variety of authors and lithographers, the whole had a consistent style thanks to the good direction Pérez Villamil with the lithographers allowed to use interpretive licenses when working from the originals..[2] The work contains 44 views of Toledo, 19 of Burgos, as well as illustrations of various places of Castile, Aragon, Andalusia, the Basque Country, Navarre, and Galicia.
