"Wordless Books" were stories from the early part of the twentieth century told in black and white woodcuts, imaginatively authored without any text. Although woodcut novels have their roots spreading back through the history of graphic arts, including block books and playing cards, it was not until the early part of the twentieth century that they were conceived and published. Despite its short-lived popularity, the woodcut novel had an important impact on the development of comic art, particularly contemporary graphic novels with a focus on adult themes.
