Léon Bellefleur traces the stages in his evolution as an artist and his concept of art. Influenced by children’s art, he held his own first individual exhibition with his children. Bellefleur was part of "Prisme d’Yeux", he describes it as a group of artists opposed to the Automatist movement and his involvement in it. Bellefleur himself was influenced by Surrealism, but rejected pure Automatism. He describes his own work as being expressionnistic, rather than abstract. He lived in Paris from 1952 to 1956, where he learnt to practice lithography that he defines as lighter and fresher than painting.
