R & Company’s celebration of post-war American craft collector Bob Pfannebecker includes nearly 70 objects by over 30 artists that are a feast for the eyes, including stunners like Patti Warashina’s ‘Deco for Kottler.’ Head of the ceramics program at University of Washington, Seattle for decades, Warashina nods to fellow professor Howard Kottler with the title of this streamlined and elegant piece from her ‘Stacked Loaf’ series. Though abstract, this stacked form resembles architecture and rising clouds. (On view in Tribeca through April 14th).
