This is a MARVEL US House Ad, from 1984, for another of their numerous toy tie-ins of the decade: STARRIORS.
The four-issue limited series was based on a short-lived Tomy toy line. Marvel also, apparently, produced a series of mini-comics that were packaged with the toys themselves.
Marvel UK passed on this property (I don't think the toys were sold in the UK, at least not under this brand name) and interest in the limited series was sparse. Copies occasionally surface in the 50p boxes.
