Vintage ad: Converse 1991

I love looking at old advertising and design. I found this Converse ad in a 1991 Sports Illustrated. The KJ photo is great, and although the copy looks like it disappears behind the photo, it actually jumps across, so none of the story is lost. The copy is also interesting in and of itself; all in all, a really cool ad. I don't know who the agency of record was for Converse at the time; anybody know?
