Between April and May 1954, one of the most ambitious expeditions of the Ethnological Museum of Barcelona, inaugurated in 1949, was organized in the protectorate of Morocco. The sculptor Eudald Serra, who was part of the expedition, wanted to model a nude bust, but local law and morality made it impossible to find any woman willing to pose. Serra did not give up; he simply looked where colonial power was absolute. With the collaboration of the Spanish authorities, he visited prisons, reformatories, and "public houses." The use of sex workers as models was systematic and deliberate in many campaigns, taking advantage of their extreme vulnerability in a context of colonial domination.
