Alexander Calder's jewellery on display

Alexander Calder is best known for his suspended abstract sculptures that silently orbit above the heads of museum goers around the world.
Calder is far less known for the approximately 1,800 one-of-a-kind pieces of handmade jewellery he created throughout his artistic career.
About 100 of those rarely seen necklaces, bracelets, brooches, earrings and tiaras are on display at the exhibit "Calder Jewelry" in the Philadelphia Museum of Art's new Perelman Building. Most are owned by the Calder Foundation and the rest are from museums and private owners.
"He was working with wire all his life," said Elisabeth Agro, the show's curator. "He first started making jewellery for his sister's dolls."
The exhibition - the first dedicated solely to Calder's jewellery -  runs till November 2 in Philadelphia. It then travels to The Metropolitan Museum of Art in New York and the Irish Museum of Modern Art in Dublin.
Each piece of Calder's jewellery typically begins with brass or silver wire that is hammered and twisted into shapes, joined in cascading dangles and sometimes adorned with glass or broken bits of porcelain.
