In 1949, Muñoz enrolled at the Royal Academy of Fine Arts in San Fernando, Cádiz, where he obtained a degree in Fine Arts. While at the school, he met Amalia Avia; they married on January 15, 1960. The first of their four children was born that year
Muñoz's first one-man exhibition was at the Sala de la Direccion General de Bellas Artes in Madrid, in 1955.
His works are in informal colours, with black predominating. The style of his later works was less aggressive, because he used other materials.
In 1964, Galería Juana Mordó was opened. He belonged to the associated group of painters from the moment of its foundation until 1991.
His works include murals for the European Union building in Brussels and the chamber of the Madrid Parliament. His mural at the Basilica of Aránzazu won the Gold Medal at the Salzburg Biennial of Sacred Art.Wikipedia
