Wear your heart on your sleeve, shirt collar, tote bag, or anywhere else you please. MoMA Exclusive: This Marcel Duchamp Enamel Pin captures a detail from Cœurs volants or Fluttering Hearts, the 1986 piece that creates an optical illusion of vibration through collage and colors. The French-American artist’s work is part of a MoMA exhibition simply titled Marcel Duchamp, the first retrospective of his multifaceted career in the United States since 1973. Made of soft enamel with a brass base and rubber clutch back, the Marcel Duchamp Fluttering Hearts Enamel Pin measures 1.25l x 1.25"w. Duchamp’s work is represented in MoMA’s collection.
