In this black and white photomontage, a telephone booth is crammed with large boulders. The inspiration for this work came to Sullivan in a dream, in 1973, and she worked through the idea of a blocked house repeatedly, with variations, in different media. From 1976 to 1979, she created a series of photomontages; in 1977 and 1978 she developed performative approaches to the same idea. Her conceptual art practice functioned through repetition, allowing her to work through an idea and elaborate different visual solutions.
