During the 1780's, Japanese merchants began marketing woodblock prints (ukiyo-e) showing sumo tournaments and champions. These prints from the mind-19th century were acquired in Japan between 1959 and 1961. They help illustrate many aspects of sumo as well as reflect the evolution of the artistic medium in Japan.
