In 1913, the International Exhibition of Modern Art, widely known as the » Armory Show », made a significant impact in New York. This event was unparalleled in scale, featuring 1,400 works and establishing itself as the largest art exhibition ever organized in the United States. It served as a crucial milestone in the progression of American art and the cultural exchange between France and the United States. The introduction of Impressionist, Fauvist, and Cubist artworks to the American public stirred considerable controversy. Notably, all nine of Villon’s paintings were sold, highlighting their immediate appeal.

After being mobilized on the second day of World War I, Villon was sent to fight on the Somme. In 1916, he transitioned to camouflage duty. Upon his return from the front in 1918, Villon resumed painting and significantly expanded his engagement with engraving. This marked the start of his abstract period, characterized by monochrome canvases and carefully selected colors. His technique involved superimposing planes to convey depth and volume, proving his innovative approach to art.
