Here’s another one of the rare ads we just couldn’t bring ourselves to delete from the archives. Straight out of 1979, this ad for “Kryptonite Rocks” is for one of those we always wanted our parents to get for us. After all, they glow in the dark! …The kryptonite, that is – not our parents. On the other hand, if you asked Superman, he would tell you that Kryptonite does NOT rock! It sucks!
