The "Knave of Diamonds" was an exhibition that opened in Moscow in December 1910, featuring French cubist paintings by Henri Le Fauconnier, André Lhote, Albert Gleizes and Jean Metzinger. Curated by Alexandre Mercereau, the exhibition included works of four Russian artists expelled from the Moscow School of Painting, Sculpture and Architecture due to their "leftist tendencies". A stated objective of the exhibition was "to offer young Russian artists who find it extremely difficult to get accepted for exhibitions under the existing indolence and cliquishness of our artistic spheres, the chance to get onto the main road."
