Alfredo Gálvez Suárez had several professions throughout his life, but he was especially talented in the arts of painting and drawing. His work is particularly noticeable in Guatemalan plastic art, for he left a legacy of anthropologic documentation with several illustrations of the life of the indigenous inhabitants of the first half of the 20th Century.

His most representative works of art are the murals that embellish the staircases, both on the east and west sides. These works of art of great dimensions display and portray elements of Mayan Culture and the clash with Hispanic Culture, giving birth to the syncretism that is present-day Guatemalan culture.
