Alfredo Jaar's preoccupation with human rights issues links together many of the artist's pieces.  The Rwandan Genocide, for instance, conceptually unifies and creates harmony not only between the various postcards below,  but also with a great many other of Jaar's works.  Jaar approaches the genocide from an interesting angle in this "postcards" piece, choosing to focus on survivors of the massacre rather than those who have died.  In doing so, Jaar not only shares an optimism surrounding the issue that is rarely communicated, it also reminds the viewer that the genocide is still very much an ongoing concern.
