Far as I can see just the back cover and the inside page. It has the girl doll from the toybox series. Great back cover. I dont know if he penciled the other stuff or not I cant find much on this comic. I can scan it if you wish. I also opened that magazine and sure enough there sits sam and max on page 94 and 95. Sort of a superhero biography fact file. Tells all sorts of stuff like height weight eyes hair, base of operations. A funny part of it is "the somewhat pathetic villains of sam and max" Also there is a picture of Purcell on the bottom left.
This magazine is called
Hero Illustrated #12 June 1994
If you find any info on it let me know. I can also scan these pages.
