Frink's absorption with the theme of heads is evident throughout her work, from the semi-abstract heads of 1959, the Dormant head and Fish head of 1961, the Soldier's head series of the mid-1960s and the Tribute heads of 1975-76. These culminate in her last heads, the monumental In Memoriam heads of 1981-83.
Talking of the development Frink explained, 'The group of heads that I started in 1975, a group of four heads with their eyes shut, are the Tribute heads and refer to people who have died for their beliefs. In a sense these sculptures are a tribute to Amnesty International. The heads represent the inhumanity of man - they are the heads of victims. The more recent heads of 1981, which I call In Memoriam and which form a pair, have their eyes open but are still an extension of the same theme: people who have been tortured for their beliefs, whatever they are. Recently I have completed another monumental head related to these two' (see Exhibition catalogue, Elisabeth Frink, Washington, National Museum of Women in the Arts, 1990, p. 53, excerpts from an interview conducted in the summer of 1984).
