even Don Heck channelling Adams. In fact, regarding the Heck issue, I remember reading several pages into it before I realized that Adams' work looked a little different, and my shock when I checked the credits. Couldn't be Heck, not possible, no way. But it was, and it was great.

X-Men 64 was the high point of Don Heck's superhero work. If he could have kept drawing like that, he would have been a popular artist.
Maybe it was the Palmer inks?

The Thomas/Adams run was great stuff. Adams art was some of his very best and Thomas seemed to finally have a grip on the X-Men.
