A powerful Art Deco cubist bronze sculpture depicting a seated accordion player, rendered in the boldly faceted, geometric idiom that made Jan and Joël Martel among the most celebrated sculptors of the French Art Deco period. The figure is reduced to essential planar forms — a helmeted or capped head tilted in concentration, angular shoulders and torso, and the accordion's bellows rendered as a dramatic fan of sharp, rhythmic pleats that becomes the sculpture's central formal statement. Cast in a rich, dark patinated bronze, the piece exemplifies the Martels' signature synthesis of Cubist abstraction and naturalistic subject matter — a stylized "everyman" musician captured mid-performance. Signed "MARTEL" to the base.

Jan Martel (1896–1966) and Joël Martel (1896–1966) were identical twin brothers born in Nantes, France, who trained together at the École Nationale des Arts Décoratifs in Paris beginning in 1912, having first studied under sculptor Pierre Vigoureux. Working from a shared studio — famously designed for them by architect Robert Mallet-Stevens at 10 Rue Mallet-Stevens in Paris's 16th arrondissement — the brothers created all of their work jointly, signing their pieces simply "Martel" or "J.J. Martel," making individual attribution between the two intentionally impossible.

The Martels became central figures of French Art Deco, exhibiting at the Salon des Indépendants, Salon d'Automne, and Salon des Tuileries, and playing a prominent role at the pivotal 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes in Paris, where their monumental concrete "cubist trees," created in collaboration with Mallet-Stevens, became one of the exhibition's most talked-about installations. They were founding members of the Union des Artistes Modernes (UAM) in 1929, aligning themselves with the movement's push toward functional, geometric modernism.

Their sculptural output spanned female nudes, animal subjects, portraiture, and genre figures like the accordion player — always reduced to simplified, faceted volumes that balanced Cubist structure with recognizable, often warmly humanistic subject matter. They also produced acclaimed public monuments, including the 1932 monument to composer Claude Debussy on the Boulevard Lannes in Paris, and war memorials throughout France. The brothers were commissioned by the French national railway for a series of modernist aluminum sculptures at the 1931 Colonial Exhibition, and their work was featured in the art competitions of the 1948 London Olympic Games.

Jan and Joël Martel were named Knights of the Legion of Honor in 1936. They died within months of each other in 1966 — Joël from illness, Jan in an accident — closing one of the most singular artistic partnerships of the twentieth century.
