[1] In Mexico, he furthered his artistic studies at the Escuela Nacional de Pintura, Escultura y Grabado "La Esmeralda", a student of Diego Rivera and José Clemente Orozco who strongly influenced his work.
Diego Rivera strongly influenced the anecdotic character of his compositions and José Clemente Orozco, with humanism and themes of the universal.
Antonio Rodríguez Luna stated “Messeguer never forgot the social concerns of the old masters, nor the most appropriate method for representing human beings (figuration): but he rejected their followers who were content to repeat what had been created by their predecessors.”[4] His works did not tell stories like that of classic Mexican muralism but they did not betray the movement pictorially or ideologically.
The work of his last ten years of life began to use paint as a malleable material, almost pastes to model in thick impastos to converge the qualities of mass, color and light.
[4] In 1962 he exhibited with Francisco Moreno Capdevila and José Hernández Delgadillo as the Nueva Presencia group, also known as the Interioristas.
