The exhibition is made up by 108 pieces reunited in the collection of Ricardo Martínez de Hoyos Foundation and other previously unknown private collections, showing the detailed and dedicated work how the painter conceived his canvases. Behind these paintings is exposed the arduous creative process of the author.

Ricardo Martínez stood out in the sphere of literary production as illustrator of books, besides his labor as painter. Perhaps, one of his most famous works is the vignette of dogs for the first edition of the book: Pedro Páramo, by Juan Rulfo.
