“When Keith and I collaborated on «Apocalypse», it was never a master-and-disciple kind of undertaking. Although Keith was young, he was not immature when it came to art. Our work was of equal weight and purpose. I found Keith’s art for «Apocalypse» completely astonishing. When I first saw his prints, it was a shock—but a good shock. My texts were perfectly understood and perfectly rendered.” (W. Borroughs, from John Gruen, «Keith Haring. The authorized biography», New York, Fireside, 1990, pag. 183)
