These drawings were made as preliminary sketches for Butler''s monument to ''The Unknown Political Prisoner'', a tower designed to commemorate those who had been imprisoned or lost their lives in the cause of freedom. The drawings represent the heads of three women, described by the artist as witnesses who remember the prisoner. Butler envisaged that the viewer would be ''drawn by their gaze into contemplation of the upper vastness of the tower.''
