An outstanding copy of the "End of Mad" issue of Mad Magazine from 1959 -- where the back of the magazine is actually the front!  Although I'm not a professional grader, I would give this a grade of Very Good.  Please SEE THE PICTURES.    There is very light wear and creasing of the front cover.   The pages are in very nice shape with just a hint of aging.  The back cover has very light wear and creasing.  All in all, a great add to your collection of a classic Mad Magazine from its very early days!
