Mound of Butter is a painting by the French realist painter Antoine Vollon completed between 1875 and 1885. A still life, it depicts a mound of butter, coloured in rich, deep yellow, with thick marks after the artist's brushwork that may be intended to suggest the marks of a butter knife. The painting is held at the National Gallery of Art in Washington, D.C.Painting: Antoine Vollon (image courtesy of the National Gallery of Art)
