The Calder Foundation has been charged with a collection of Calder works that is unsurpassed in both scope and depth. This collection is comprised of thousands of pieces from all periods of Calder's life. It includes more than 450 sculptures (including mobiles, stabiles, standing mobiles, and wire sculptures), and 35 monumental outdoor works, as well as oil paintings, works on paper, toys, pieces of jewelry, and household objects. At any given time, a large number of these works are on public view, either in traveling exhibitions or on long-term loan to institutional collections (see Events).
