A boy stands between a "Kiliki" and a "Cabezudo" during the San Fermin festivals "Comparsa de gigantes y cabezudos" (Parade of the giants and the big heads) in Pamplona. "Kilikis", wearing outsized masks and playfully hitting bystanders with sponges on sticks, parade daily through the city accompanied by brass bands during the nine-day-long festival made popular by U.S. writer Ernest Hemingway.
