Alexander Calder (1898-1976) was an American artist whose radical, kinetic approach to sculpture revolutionised the medium. Most famous for his 'mobiles', Calder's work explores the relationship between form and movement. Bold, primary colours complete the iconography of his work.
Calder was also one of many prominent artists to collaborate with the New York branch of Atelier Mourlot. His whimsical designs were featured on lithographic posters to promote the new studio.
