opening exhibition in the Museo del Chocolate (Chocolate Museum) in Mexico City on 22nd March 2012. His exhibition, Del Choco que Late ("Mad for Chocolate") contained twenty-two works that interpreted chocolate as a metaphor for desire and prohibition. This exhibition was followed by Deseo... ese obscuro objeto (Desire, That Obscure Object), which was presented by the gallery Diego de Ybarra & Natalia Davila Fine Art in Mexico City. That same year he drew thirty-five portraits of the singer Chavela Vargas, whom he had met a year earlier in Tepoztlán, Morelos. The collection was exhibited in June 2012 at the Centro Cultural de España en México, Mexico City. In March 2013 Del Valle presented the commemorative exhibition honoring the twentieth anniversary of the Museo Felipe Santiago Gutiérrez of the Instituto Mexiquense de Cultura, in the city of Toluca.
