X-Men #120 features lots of appearances, but most importantly it is the 1st cameo appearance of Alpha Flight!  Sunfire, Mariko Yashida, Misty Knight, and Colleen Wing also appear.  This one is tough in high grade due to the dark purple cover.  Art by John Byrne and story by Chris Claremont.  This book is graded 9.6 NM+ with white pages by CGC.  It has very nice alignment, too, making it a super copy!
