Portrait of Josefina, a resident of Casa Xochiquetzal, in her room at the shelter in Mexico City on March 14, 2008. Casa Xochiquetzal is a shelter for elderly sex workers in Mexico City. It gives the women refuge, food, health services, a space to learn about their human rights and courses to help them rediscover their self-confidence and deal with traumatic aspects of their lives. Casa Xochiquetzal provides a space to age with dignity for a group of vulnerable women who are often invisible to society at large. It is the only such shelter existing in Latin America.
