These are LUG (not "Lugo") French editions. From what I get, they had some different formats, and published the characters in a pretty confusing rotations, most of those have custom covers painted by French artists, which are occasionally very nice. I seem to recall X-Men was mostly the main feature on "Strange", while the Specials (as yours) published characters in rotation. If you remind me, I can post a sample later on, as I have some eBooks of those.
Special Strange was the main home for Uncanny X-Men . It reprints #154 & 155. There was also Marvel Team-Up #103 & Marvel Two-In-One #65.
At that time (1985), there was a 4 years difference with the US so some UXM issues were also published in another publications (X-Men album).
Most of the Frenche reprints were cover painted by Jean Frisano.
