Each pen is attached to the ceiling by a chain and also attached to the carriage return on the machine. When the viewer inserts a sheet of paper and presses the indicated keys, a copy of letter from the 1930's is typed.
At the same time, the pens are pulled over another sheet making a random drawing to the right of the typewriter.
One letter is from Jackson's brother Sanford to art patron Helen Marot and the other from Dr. Henderson, Pollock's psychiatrist, also addressed to Ms. Marot.
