This in very good condition with minor wear on the staples.  I have three of these for sale in similar condition, but the last one sold the cover is off a bit by the staples which I show in my second photo.  (The reason these are a bit stressed by the staples is because when this was made, they put a Giants Calendar 1988-1989 which is still inside all of these.)  Please look closely at my photos for details.  Item 1069, 1070, 1071
