Which Pop artist created the 1967 sculpture 'Love' (LOVE logo)?

Which Pop artist created the 1967 sculpture “Love” (the LOVE logo)? Robert Indiana created it.

Indiana’s LOVE design places the letters L and O above V and E, with the O tilted diagonally. Although the question identifies a 1967 sculpture, the design’s development began earlier: Indiana first used the image on a card in 1964 and on a Museum of Modern Art Christmas card in 1965.

The first LOVE sculpture was made in aluminum in 1966, while Indiana completed the first monumental Cor-Ten steel version in 1970. The design’s bold typography, intense colors, and instantly readable word made it one of Pop Art’s most recognizable public images.

A common mix-up is to credit the sculpture’s production date with the design’s origin. Another neighboring fact is that Indiana later made versions spelling “AMOR” and the Hebrew “AHAVA.”
