Superman vs. Metallo [Kellogg's Cinnamon Mini Buns]
DC · 1993 · 1 issue
About the series
A one-issue promotional giveaway from 1993, this DC comic was produced as a tie-in for Kellogg's Cinnamon Mini Buns. It pits Superman against the kryptonite-powered villain Metallo in a straightforward, all-ages adventure. While a minor curiosity in the Man of Steel's long history, it stands as a unique piece of 1990s corporate cross-promotion within comics.
