Delta. A Piece is the video documentation of a performance at the 1977 exhibition Kunstlerinnen International 1877-1977, in Berlin. EXPORT, wearing face-paint, writes words in chalk on a raked blackboard. She attaches sculptural objects to her body, which seem to hinder her writing. She later smudges and erases her words. During the performance a repetitive male voice booms out aggressively.

Writes VALIE EXPORT, "Departing from shoulder and hand symbolism as historical body language, the history of woman in the world of the man is forced open."
