One of the central figures of the Pop Art movement, Robert Indiana takes his inspiration from commercial signs, claiming: ââ¬ÅThere are more signs than trees in America. There are more signs than leaves. So I think of myself as a painter of American landscape.ââ¬Â In his paintings, sculptures, and prints, he mimics and re-arranges the words and numbers of a myriad of signs, including the Phillips 66 gas station logo and the ââ¬ÅYieldââ¬Â traffic sign. He is most famous for his ââ¬ÅLOVEââ¬Â paintings and sculptures, first produced in the 1960s. Creating a block out of the wordââ¬âwith the ââ¬ÅLââ¬Â and the ââ¬ÅOââ¬Â set atop the ââ¬ÅVââ¬Â and the ââ¬ÅEââ¬Âââ¬âIndiana has effectively inserted his own sign into the mix.
