A drawing by schoolboy Petr Ginz, killed in Aushwitz in 1944, will be featured on a new stamp to be unveiled in Prague on Thursday, reports BBC News. The pencil sketch depicts mountains on the moon with the earth shining in the distance and is part of Yad Vashem‘s permanent art collection in Jerusalem. That it was drawn 25 years before such an image was confirmed by astronauts makes us wonder sadly what else Ginz might have accomplished. May his vision of of one planet inspire us to keep peace in mind.
