The Tsuchigumo (土蜘蛛), or earth spider was one of the Japanese malicious spirits known as Yōkai (妖怪). Here, the earth spider torments the Fijiwara clan warrior Minamoto no Yorimitsu — filling his dreams with wicked beasts and monsters, while his retainers, unaware, play the Chinese strategy game of Go. In its day this was a controversial print — seen as a caricature of Shogun Ieyoshi. The original wood blocks for the print were burned, but Kuniyoshi replicated the blocks and continued to publish the prints. Fight the power Kuniyoshi.
Works in the public domain are those whose intellectual property rights have expired, have been forfeited, or are inapplicable. Artworks and writings enter the public domain when their copyright expires. Determining when a work's copyright expires is complex, but in general a work is in the public domain in the U.S. when it was created before 1923, and in most countries when the artist/author has been dead for 70 years. For these works, unlimited copy, distribution, modification, and reuse are allowed for free. More About Public Domain
