At that time, Ibiza was home to a colony of artists, writers, and expatriates predominantly from Europe and North America.
While on Ibiza, Munford helped found Grupo Ibiza 59, an artist group that included Erwin Bechtold, Erwin Broner, Hans Laabs, Katja Meirowsky, Egon Neubauer, Antonio Ruiz, Bertil Sjöberg, and Heinz Trökes.
His work, La Vigie, featured in Munford's 1960 Paris show at the Galerie Lara Vincy, is an example of this period of production.
[1] Between the years 1957 and 1964, Munford, in a series of gouache and oil paintings, moved towards a distinctive proto-pop style, his work of this period now being characterized by the use of cloudy atmospheres, silhouetted figures, and pop art elements, such as handwriting, numbers, diagrams, repetitive stamped images, and photographic transfers.
Between 1968 and 1970, Munford designed stage sets for the Michael Abrams Gothic Art Theater, the Brooklyn Academy of Music, the Elliot Feld American Ballet Company, and the New York City Center.
In 1970, he was commissioned by Great American Editions to create a series of silkscreen prints depicting circus scenes.
