⚠ AI-Estimated / Approximate Condition Profile

Cover shows strong gloss and vibrant color with sharp corners and no visible creases or spine stress lines. Slight edge wear may be present at the extreme corners but is difficult to confirm through the protective sleeve's glare. The book is in a plastic protective sleeve, which limits full assessment of edge and spine wear; interior pages and back cover were not visible for evaluation.

// Archive commentary

Uncanny X-Men #278 arrived during the tail end of the Muir Island Saga, the multi-issue arc in which the Shadow King's psychic dominion over Muir Island is broken by the combined X-Men and Excalibur teams. Written by Chris Claremont with art by Jim Lee and inks by Scott Williams, the issue is a representative example of the Claremont/Lee collaboration that defined Uncanny X-Men's final stretch before Lee's departure to launch the adjacent X-Men #1 series. The issue does not introduce a new character, costume, or plot element cited as a notable first, and its significance rests on being a well-drawn chapter of a fondly remembered storyline rather than a landmark single issue.
