In 1970, Castoro developed a series of freestanding panels that occupied the space as sculptural forms. Their surfaces were created from plaster applied with a broom, which was then covered with graphite shading, so that the works combined painting, sculpture and drawing.

In stating that ‘my panels are my containers’, Castoro clearly indicates the importance of the body in her practice. Indeed, the artist took numerous photographs that she pasted in her journals and which show her adopting dance poses within her works or interacting with ropes suspended in front of them.
