Down to the last two CC ads posts. I think most people's favorite CC ads were the Don Post mask ads, because it was the coolest monster product and few of us could afford them (or one), making them even more desirable.
This was the first color ad of the "calendar" masks, from the back cover of FM #33 (and #34). The later color ads used the calendar photos.
This, however, was my favorite DP ad. I think this ad only ever appeared in b/w. The masks just looked more "real" in b/w.
