Batman #242 features an awesome Michael Kaluta cover and begins an epic Ra's Al Ghul storyline, and as such, it is an emerging minor Bronze Age key!  The book is also very rare in this grade.  There are only 6 copies graded higher in the CGC census (at 9.8) and there exist only 20 copies in this grade.  This book is graded 9.6 NM+ with white pages by CGC.  The alignment, color and gloss are all excellent.
