Uncanny X-men #129, Marvel Comics 1980, 1st appearance Kitty Pryde, Emma Frost and Sebastion Shaw, huge X-men Key!  Nice looking copy in my opinion, please look at scans in order to determine grade/condition for yourself.  Specifically, front cover there is an ink smudge on the letter N in X-men, slight spine wear below top staple, spine tick above bar code and some slight corner wear.  Back cover has a few non-color breaking creases on the spine and bottom left quarter.  Overall a nice book in my opinion that could be helped by a pro clean and press.  Great key for the collection, shipped USPS via Gemini Mailer, Thanks for bidding!
