Léon Ferrari. This contemporary Argentine artist was made Honorary Guide on January 10, 2005, for his most famous work, La civilización occidental y cristiana (“Western-Christian Civilization,” 1965), in which Christ is shown crucified on an American warplane as a symbolic protest against the Vietnam War. Ferrari has also created works deemed offensive by the Catholic Church, and one of his exhibitions was forced to close in Buenos Aires after a Catholic priest obtained a court order.
