This series of sculptures in reference to the Nigerian Civil War or otherwise known as "Biafra War", displayed a departure in his style, which began to dramatize social and global problems. "¿Biafra?" has its sad moment of inspiration in hunger and death that ravage that area of Africa, although it is obvious from the title itself to these scourges re probation anywhere. Pujía said: these works are a reflection of the scourge of hunger, I focused on the Biafran guys, but the meaning was wider... because I think that a scourge of this kind is the most unfair thing that we humans can make, with the hunger of our children who are totally helpless and dependent on us. A casual observation of a photograph of a child in Biafra was triggering the theme of this Pujía´s work. The search for a categorically own image emerged as something long matured, hurt by the painful stimulus. The series of bronze and other materials which the author called ¿Biafra? is among the most valuable of Argentina sculpture of all time.
