>>116818904It wasn't much of an imprint, but rather a literal label
>Suggested for Mature ReadersThat label had mostly died out by 1993, with the exception of a bunch of more-fantasy-like titles like Sandman, Shade - The Changing Man, and Doom Patrol. So those remaining titles got shifted to Vertigo.
Green Arrow was Suggested for Mature Readers for most of Grell's run, but the last year or so shifted back to "all ages."
That label itself was why Alan Moore officially never wanted to work for DC again because he felt that it would lead to censorship. He, along with Frank Miller, Howard Chaykin, and Rick Veitch refused to work for them after that.
Veitch was convinced to come back, but then quit until 2001 because of the fuck up with Swamp Thing 88.
