Comic Book Talk
Ha, actually, I forgot that Sandman actually predated the Vertigo imprint and was later grandfathered into the line about halfway through its run.. So those issues are actually from 1989. But Sandman was Vertigo before Vertigo was a thing (Karen Berger, who basically founded Vertigo, gave Gaiman the Sandman gig when she was editing for DC proper). It influenced the line as a whole as much as any book could have.
