Robert Indiana; born Robert Clark (September 13, 1928 – May 19, 2018) was an American artist associated with the pop art movement. His "LOVE" print, first created for the Museum of Modern Art's Christmas card in 1965, was the basis for his 1970 Love sculpture and the widely distributed 1973 United States Postal Service "LOVE" stamp. He created works in media including paper (silk screen) and Cor-ten steel.

One of the preeminent figures in American art since the 1960s, Indiana played a central role in the development of assemblage art, hard-edge painting, and Pop art. A self proclaimed “American painter of signs,” Indiana created a highly original body of work that explores American identity, personal history, and the power of abstraction and language, establishing an important legacy that resonates in the work of many contemporary artists who make the written word a central element of their oeuvre.
