Amazing World Of DC Comics #13 [1976]

Steve Ditko drew one story published in DC's humour anthology PLOP, but there was another story intended for it, done with the same writer (Steve Skeates) and inker (Wallace Wood). "The Gnark Is Coming! The Gnark Is Coming!" instead appeared in AMAZING WORLD OF DC COMICS #13 [1976]. It's one of the few Ditko stories for DC never to be reprinted.

The 4-page story is set in medieval times and features a would-be squire named Bruce who gets conned by a bunch of frightened knights into dealing with the mysterious "Gnark" that, as the title says, is coming. Cute little story, the artwork shows some pretty heavy inkwork typical of Wood in this period, but still pretty clearly Ditko underneath.
