What is the medium that Claes Oldenburg use?

Claes Oldenburg is known for his monumental sculptures, often of everyday objects. His primary medium is soft sculpture, which is made of fabric, vinyl, and other flexible materials. He also works with paint, plaster, and bronze.

Here's a breakdown:

* Soft sculpture: This is his most defining characteristic, creating life-sized or larger-than-life versions of ordinary things like hamburgers, pencils, clothespins, and ice cream cones. He often uses bright colors and playful forms.

* Paint: He sometimes uses paint to finish his sculptures, but it's not his primary medium.

* Plaster: He has used plaster in some of his sculptures, especially early on in his career.

* Bronze: He has also cast some of his sculptures in bronze, creating more durable and permanent versions of his soft sculptures.

Oldenburg's work challenges traditional notions of sculpture and explores themes of consumerism, popular culture, and the relationship between art and everyday life. He often plays with scale and materiality, creating a sense of whimsy and wonder in his work.
