xylograph:
Kunyu wanguo quantu, or Map of the Ten Thousand Countries of the Earth, is the oldest surviving Chinese map to show the Americas. It is a xylograph (wood block print) on six scrolls of fine native paper, each scroll measuring approximately 1820 x 3650 mm (each panel is approximately 2 feet by 5.75 feet). The carving of the wood blocks was done by Zhang Wentao. [University of Minnesota / James Ford Bell Library]
