Robert Indiana (1928-2018) was an American artist, sculptor and printmaker. His most famous artworks are probably paintings and sculptures depicting the word love in capital letters, bright colours and tilted letter o. The artist started using the motif in the mid 1950s and he also made artworks from numbers. Therefore he could be seen as an American painter, who created signs. The signs are tied to the fact that Indiana’s childhood contained a lot of moving, therefore he spent a lot of time on the highway. Indiana had a highly unconventional style. His oeuvre has been a huge contribution to using written word as a central part in the artworks in general.
