Book dedicated to Mexican artist Francisco Toledo (b. Oaxaca, México 1940) comprising ceramics of high temperature. The cases of disappeared students in Iguala and Tlatalya (Guerrero), as well as the disappearances in the 1970's and the social movements in Oaxaca in 2006 were the main inspiration of the artist, environmentalist and social activist in the exhibition "Duelo" (Grief), with allusions, sometimes direct, as in the case of the color red that characterizes much of the works on display.
