Averaging[clarification needed] the 2nd World War, the group proposed a rupture as an alternative.

In 1951 he traveled to Europe and met Vantongerloo in Paris and Vordemberge-Gildewarth in Amsterdam, who guided him in his pursuit.

Upon the dissolution of the group, Espinosa left the common goals but remained faithful to the spirit of non-figuration and produced a painting constructed from geometric elements, characterized by a rigorous system of order and by the perfection of their registers.

Clarity, moderation, are attributes of his painting, which with minimal elements arranged serially produce subtle effects of color and space and a dynamic tension that creates an impression of depth.

He is one of the painters who most enjoys the game aroused by reason and sensitivity, a consequence of his special relationship with music and literature.
