In this episode of Expert Voices, David Galperin sits down to discuss the sculptural revolution of Alexander Calder’s magnificent artwork, Mariposa. The sculpture, an artistic masterwork as well as feat in invention, reflects the artist at the height of his career. Calder, one of the most notable artists of the 20th century, bridged the gap between sculptor and innovator – in effect, occupying a diversity of roles as an artist. Mariposa is a highlight of the upcoming Impressionist, Modern & Contemporary Art Evening Sale (8 December 2020, New York).
