"Intimacy" is not a word that first comes to mind when thinking about Alexander Calder's steel work. But when you step inside Dominique Levy's immaculate townhouse galleries on the Upper East Side, where some 40 rarely-seen Calder maquettes are on view, intimate is exactly how it feels.

Collaborating with architect Santiago Calatrava Lévy presents two floors of Calder's miniature (the smallest work is 1.5 inches tall) to table-top sized sculptures. Many have not been on view since his MoMA retrospective in 1943.
