Answer: "The Store"
Step-by-step explanation:
The name of Claes Oldenburg's first New York exhibit was "The Store", which was held at the Green Gallery in 1961. This exhibit featured replicas of everyday objects, such as food items, tools, and clothing, made from a variety of materials including plaster, wood, and fabric. The objects were arranged in a makeshift store, which allowed visitors to purchase the items. This exhibit marked Oldenburg's transition from painting to sculpture and ultimately established his reputation as a Pop artist.
