Bully the little stuffed bull, with help from his friend John DiBello, ran a DC subscription ad from 1972 the other day on his blog Comics Oughta Be Fun! as part of the 365 Days of DC House Ads feature.

I wasn’t quite reading comics at fourteen months old in December 1971, when the
issue from which this ad was taken — Batman #239, cover-dated February 1972 — was published. But I’ve seen it in back issues acquired since then and I know that it was repurposed, directly as well as in concept, over time.
