Claes Oldenburg's "Huge Safety Pin" is primarily made of painted aluminum. The sculpture is a large-scale representation of a common safety pin, emphasizing its everyday significance and transforming it into a monumental work of art. The use of aluminum allows for a lightweight structure while maintaining durability and weather resistance, making it suitable for outdoor display.
Well when he first moved into America he joined a club of artists. They decided they would make a sculpture. He so liked the idea he created his own group that focused on making sculptures. Claes Oldenburg started them off with small plaster models of sculptures and then after perfecting them time after time he disscussed with them about the idea of making a large-scale sculpture. The club liked the idea so much they couldn't refuse. And from then on he made large sculptures as work.
