Green Lantern #87 has so much to offer!  This is a HUGE KEY.  It's the first appearance of John Stewart, the second appearance of Guy Gardner, and it is part of the vaunted Neal Adams run which began in #76.  This one has a Neal Adams cover and interior art.  The book is graded 9.6 NM+ with white pages by CGC.  The alignment, color, and gloss are stunning.  This one is tough because of the white cover...and this one is very white!  I'm not sure why this didn't make a 9.8!
