Calder and Louisa travel to Otterlo for the Kröller-Müller museum commission. The project for which Calder creates a maquette, is never executed.
In 1963, Calder completed construction of a large studio overlooking the Indre Valley. With the assistance of a full-scale, industrial ironworks, he began to fabricate his monumental works in France and devoted much of his later working years to public commissions.
