The two images below were produced by dripping ink drops down a stairwell (approx 90 foot drop) at the original Central School of Art in Holborn.

One was produced in 1975 and the second in 2010.

On the second sheet the ink was released from as near as possible to the original position at the top of the stairwell and dropped on the next page of the same sketchbook, the page not having been turned for 35 years.
