Robert Indiana

Robert Indiana (born as Robert Clark; September 13, 1928 – May 19, 2018) was an American artist. He was known for being a part of the pop art movement. He was born in New Castle, Indiana.
Indiana moved to New York City in 1954 and joined the pop art movement. Indiana's work often has bold, simple, iconic images, especially numbers and short words like "EAT", "HUG", and "LOVE". His sculpture in the lobby of Taipei 101, called "1-0" (2002, aluminum), uses multicolored numbers.
After the September 11, 2001 attacks, Indiana made a series of "Peace Paintings", which were shown in New York in 2004.
Indiana died on May 19, 2018 in Vinalhaven, Maine of respiratory failure at the age of 89.
LOVE.
Indiana's best known image is the word "love" in upper-case letters, arranged in a square with a tilted letter "O". This image was first created for a Christmas card for the Museum of Modern Art in 1964. It was put on an eight-cent US Postal Service postage stamp in 1973, the first of their regular series of "love stamps."
Sculptures of the image can be found at many places in the United States:
