Alvar Sunol Munoz-Ramos was born in the Catalan fishing village of Montgat on the Spanish Mediterranean coast, in 1935. He started painting oils at the age of twelve, and at age seventeen was accepted to Escuela Superior de Belles Artes in Barcelona. During this period, on of his paintings was acquired by the Museum of Modern Art in Barcelona as part of its permanent collection. Before graduating from the Belles Artes, he was given his first one-man show in Barcelona, in 1957. In the following year, the Institut Francais awarded him a scholarship to study in Paris, where he eventually studied for a number of years.
Since a decisive one-man show in Paris, 1963, he has exhibited regularly throughout Europe, the United States, Canada, and Japan. In 1978, a retrospective exhibition of his lithographs was held by the Musee Hyacinthe Rigaud in Perpignan, France. His lithographs, paintings, and sculpture have been presented in major shows at the Utah Museum of Fine Arts, Salt Lake City, 1982, and the Wichita Art museum of Fine Arts, 1983. The Kumamoto Museum and the Fukuoka Museum, both in Kyushu, Japan, have purchased his lithographs for their permanent collections.
In 1993, an important book devoted to the artist's paintings was published in Spain and the United States. In that same year, ten one-man shows exhibiting the artist's works in all media (paintings, graphic works, sculptures, and drawings) were held throughout the United States.
