From February 1988: The MARVEL UK teaser ad for the about-to-launch THE REAL GHOSTBUSTERS. It's an obvious design... but also incredibly strong.
TRG turned out to be a real cash-cow for the Annex of Ideas. Not only was the core book a runaway hit but it also spun off the traditional Collected Comics and annuals.
Marvel also published books, a poster magazine, a best-of monthly and the spin-off BLIMEY IT'S SLIMER monthly and specials.
The Big Green Ectoplasm also popped-up in the short-lived all-original humor weekly IT'S WICKED and the Ghostbusters were also mainstays of THE MARVEL BUMPER COMICS anything-goes anthology.
