During the 1960s Tilson became one of the leading figures associated with the British Pop Art movement. Making use of his previous experience as a carpenter and joiner, Tilson produced wooden reliefs and constructions as well as prints and paintings.

His first one-man show was held at the Marlborough Gallery, London in 1962. In 1977 he joined the Waddington Galleries and also exhibited at the Alan Cristea Gallery and the Giò Marconi Galleries in Milan. Tilson's work gained an international reputation when shown at the XXXII Venice Biennale in 1964, which led to a retrospective at the Boyman's Museum, Rotterdam in 1964. Further retrospective exhibitions followed at the Vancouver Art Gallery in 1979 and the Arnolfini Gallery, Bristol in 1984. Growing disillusionment with the consumer society led to a change in Tilson work in the 1970s. After moving to Wiltshire in 1972, Tilson began to use a wider variety of materials, including stone, straw and rope in an effort to transcend time and culture by drawing on the motifs of pre-Classical mythology. This body of work was called Alchera.
