Final answer:
The memorial sheet for Karl Liebknecht by Käthe Kollwitz is a monochromatic woodcut that focuses on the mourning of the masses, particularly the women and children, with a stark contrast and expressive emotion.
Step-by-step explanation:
The intended form of the memorial sheet for Karl Liebknecht created by Käthe Kollwitz in 1920 was a monochromatic woodcut. Kollwitz employed woodblock printing, a technique she favored for its ability to convey strong emotional content through stark contrasts and rough edges.
The work memorializes the Communist leader Karl Liebknecht following his assassination, focusing not on Liebknecht himself but on the masses, specifically the mourning women and children who symbolize those broadly affected by the tragedy, reflecting a recurring theme in Kollwitz's work. This woodcut is pronounced for its heightened contrast with white and black ink, which emphasizes Kollwitz's expressive capacity to depict the human condition and the sorrow of those left behind.
