Earth Postage Stamps--Peacemaker Series #'s 10 through 12

Three more stamps in my imaginary Earth Postage series dedicated to Peacemakers. Joining the first nine: Bob Marley, Steve Biko, Helen Keller, Mary Harris "Mother" Jones, Raoul Wallenberg, Sojourner Truth, Thich Quang Duc, Allama Mashriqi, and Rachel Carson, are Sediqeh Dowlatabadi, Mychal Judge, and Paula Gunn Allen.

I'm imagining eventually extending this series to 100.
