The series Litografias de Madrid (Lithographs of Madrid), is a collection of twelve stone-cut black ink lithographs by the artist and colourized in watercolours by the hand of the artist. Every lithograph is signed recto by the artist in graphite in the lower right corner. Each image is titled with the original title given by the artist, plus the English translation. It is unknown to us how many of these were printed, but they were published in 1963 with Spanish accompaniment (published by Rafael Díaz Casariego, Madrid).
