Henri Clément Serveau, also known as Clément-Serveau, was a French painter, designer, engraver and illustrator. Clément-Serveau produced works in a realist manner early on, but soon became interested in the new movements. He was influenced by his friend Louis Marcoussis and experimented with Cubism, utilising geometric patterns to give the illusion of form and space. Later in his career, he turned toward abstraction with a post-cubist stance. He designed banknotes for the Banque de France, produced large murals and participated in numerous French and international exhibitions.

Louis Marcoussis, formerly Ludwik Kazimierz Wladyslaw Markus or Ludwig Casimir Ladislas Markus, was a Polish-French avant-garde painter active primarily in Paris. Markus studied law in Warsaw before attending the Kraków Academy of Fine Arts, and later moved to Paris to study under Jules Lefebvre at the Académie Julian. His work was first featured in a major exhibition at the Salon d'Automne in 1905. In Paris, he became acquainted with prominent artists of the School of Paris and writers in the cafes of Montmartre and Montparnasse.
