’18 Women: 50 Years’ at Michael Rosenfeld Gallery is a tour de force of painting and sculpture, ceramic, textile and work in a variety of media created between 1918 to 1968 by some of the most influential artists of the mid-20th century. Among the many standout pieces is Ruth Asawa’s S.391/50, a crocheted brass wire sculpture from c. 1958, which the gallery describes as taking the form of ‘six double-sided, trumpet-like shapes that expand outward from the central void’ in a dynamic composition of repeated looping line. (On view in Chelsea through Jan 25th. Note that gallery hours change during the holiday period.)
