You can order this print here [if there are any left. I ordered mine back on May 23rd, yay me].
From Andrew Sullivan's most excellent blog:
A reader writes:
Tomorrow I will go to the African American cemetery outside of Chicago where my great-grandparents, grandparents, aunts, uncles, friends, neighbors, and my mother and father are buried. And I will tell them that they were right -- that if we studied hard, worked hard, kept the faith, fought for justice, prayed, that this day would come.
And it has.
