Adding two books

[Rafa]

Hi! I suggest adding ISBNs 9788419018175 and 9788419018168. These form a pair of great little books, Soldado Rojo and Soldado Azul, with a compilation of the written materials that Republican and Nationalist fighters were given to carry in their backpacks during the Spanish Civil War. A piece of history! Thank you.
