Mortar and pestle brooch

During a yearlong stay in Aix-en-Provence, Calder executed the first group of large-scale outdoor works and concurrently concentrated on painting gouaches. In 1954–55, he visited the Middle East, India, and South America, with trips to Paris in between, resulting in an astonishing output and range of work. Toward the late 1950s, Calder turned his attention to commissions both at home and abroad.
