Robert Indiana, the American artist closely associated with the Pop Art movement, is best known for his iconic LOVE image, which has become one of the most recognisable works of 20th-century art. Using bold typography, bright colours, and simple yet powerful compositions, Indiana transformed language into art, exploring themes of identity, spirituality, and the American experience. While LOVE remains his most famous creation, his wider body of work includes the Numbers series, political posters, and large-scale public sculptures, all of which reflect his interest in words as both symbols and visual form. His works are represented in major museum collections around the world and continue to resonate as cultural touchstones.
