It seems that more than one person works as JR, and who or what JR is isn't made clear by the web site. Regardless, JR is doing amazing work calling attention to the plight of women living in conditions of extreme poverty, violence, rape, and other challenges in Africa and South America. The images below are from a month of taking photographs and working in a Rio de Janeiro favela. JR photographed the faces of women from the area, enlarged the photos, and then put them up giving the hills of the favela the women's giant watchful gaze. The image on the steps is one of my favorite. Truly amazing!
