Illinois Wesleyan University, Hispanis Studies, sitio web, 18 enero 2017: (Álvaro Ángeles Suman has exhibited his work in Mexico, the United States and Spain. Critics have argued that the use of traditional Mexican motifs gives the work of Suman a distinctive tone, generally associated with the work of the well-known artist, José Guadalupe Posada, and with the artistic tendencies explored by the Mexican muralists. The recreation of Mexican cultural icons in a contemporary style makes Suman the perfect artist to capture in color and form the words so masterfully narrated by Luis Leal.) https://www.iwu.edu/hispanic-studies/luis-leal/about.html
