The latest showcase for mid-century design is -- surprise, surprise -- a new condo. Called White Space, it is billed as a "global address" but can more accurately be found at 650 Sixth Avenue at 20th Street. Earlier this month, this new real estate development debuted its sales office to the public chockablock with pieces by George Nakashima and Piero Fornasetti, courtesy of the Chelsea gallery Sebastian + Barquet. Artworks were provided by Jack Shainman Gallery.
