Robert Indiana occupies one of the front ranks among the leading Popo-artists. Robert Indiana became famous with works of art in which he strikingly displays simple and catchy words like "Love", "Hope" and "Eat", the "Peace" sign or just numbers. Besides sculptures and paintings, graphic art also counts among the US-American artist's preferred means of expression. He made, among others, brilliant silkscreens. Gaudy and eye-catching signal colors are the most striking characteristic features of Robert Indiana's works. Additionally, the extremely precisely executed contours and color fields, particularly in his paintings, also captivate the observer. It is for those reasons that Robert Indiana's art is at times ascribed to the 'Hard Edge'.
The unmistakable artworks by Robert Indiana are represented by the most renowned museums and collections, e.g. the New York Museum of Modern Art or the Walker Art Center in Minneapolis.
