At once invoking spontaneity and awesome grandeur, Blue Moon stands as a triumphant masterpiece within Calder’s singularly inventive body of work. The artist’s gong hanging mobiles are a rarity and highly significant within the artist’s sculptural oeuvre. One of very few examples remaining in private hands, the present work is also distinguished by its scale, as among the largest gong mobiles that Calder ever executed.

Presented in partnership with Celine, this breathtaking mobile features in the Modern Evening Auction taking place at Sotheby's New York on 16 May.
