'Cho Juaá: Collective Humor' is an exhibition dedicated to reviewing and reappraising the career of Eduardo Millares Sall (Las Palmas de Gran Canaria, 1924–1992), considered one of the most significant and influential Canarian artists of the 20th century for his staunch championing of avant-garde caricature and his role as a founding member of the Agrupación Vanguardista Canaria de Caricaturistas Personales.
