I carefully pull the sheets of paper out of the tube and place one against his stone. With the charcoal I rub over the paper. I rub quickly in short, even strokes. Slowly, letter by letter, number by number, the image appears on the paper. I rub the whole sheet over again. I roll this sheet up. Then, with another sheet, I begin again. Twice more I rub out his headstone onto the paper. I take my time, wiping my hands clean before I go. I scrub each finger individually, even the nails.
