From December 1986: a double-dose of MARVEL UK giant robot goodness: side-by-side (or, more accurately, stacked) House Ads for the TRANSFORMERS: THE MOVIE POSTER MAGAZINE and the one-and-only ZOIDS ANNUAL.
The Poster Magazine (reviving an old publishing tradition, occasionally indulged by the Annex of Ideas) was a giant version of the stunning key advertising art with, if I recall correctly, a summary of the movie on the reverse illustrated by cells/ stills from the animation.
M-UK also reprinted the three-issue movie adaptation in a done-in-one album-format special.
The Zoids Annual was a spin-off from SPIDER-MAN AND ZOIDS weekly (Spidey also had his own annual... I'll post the House Ad for that soon) with all new material. At this time, the Bullpen were canny (or foolhardy) enough to tie the yearbooks into the ongoing continuity of the comics making them even more of a must-have for regular readers.
