The album of chromolithographs, 'México y sus Alrededores' (Mexico and Environs), is online at NYPL. The principal lithographer/artist for the project was Casimiro Castro, one of Mexico's foremost landscape artists in the nineteenth century. The forty illustrations were originally published in 1855-1856 [available at Biblioteca Virtual Miguel de Cervantes (click 'leer'), which includes the text]. The version at NYPL was published in 1869.
