His installation art often featured repetition and mass production techniques, reflecting the consumer culture of his time. His famous works include the 'Campbell's Soup Cans' and 'Marilyns', which he created through silkscreen printing. Installation art typically involves large-scale works that transform or alter a space for a temporary period, often for an exhibition.
