What is "tubism"

Tubism is a term coined by the art critic Louis Vauxcelles in 1911 to describe the style of French artist Fernand Léger. Meant as derision, the term was inspired by Léger's idiosyncratic version of Cubism, in which he emphasized cylindrical shapes. The style was developed by Léger in his paintings of 1909–1919, such as Nudes in the Forest (1909-10) and The Card Players (1917).
