This motley assembly of masked Marvels appeared as a full page photo-poster in THE EXPLOITS OF SPIDER-MAN issue 18 (cover-dated 9 February 1994) and - presumably - shows the entire contents of Arundel House's dressing-up box.
I assume it was taken on the roof of the Annex of Ideas, as previously seen in the Spider-man photo-strip that I posted way-back-when last year (here).
For some reason my eye is particularly drawn to Wolverine.
Marvel UK used these costumes for a number of personal appearances around this time. I posted a video of their appearance in the London Lord Mayor's Show here and I have some more scans, again from The Exploits of Spider-man, still to post.
I immediately assumed these were Marvel UK staffers of the period but - equally - they could have been models hired for the day. Does anybody recognise anyone from this rouges gallery?
