During the 1950s King's sculptures were influenced by such earlier artists as Michelangelo, Rodin and Picasso. In 1960, he scrapped all his previous work as a result of seeing American Abstract Expressionist painting. The new American painting seemed to King to contain 'a sort of message of hope and optimism, large scale, less inbred'. Qualities of wit and humour, and largeness of scale, are characteristic of the abstract sculptures which King then began to make. 'Green Streamer' was made at the end of the 1960s when King was seeking to introduce a greater sense of space in his work. Its arrangement of curves vividly evoke an impression of movement.
