I am selling a RARE Mighty Mouse Sealed 1977 Childs Writing Board Double Film Slate Black Board.  This item is really neat and originally cost 59 cents.  Even though it still has the plastic seal on it, there are some areas where the seal was torn or not covering the board.  There is a tear on the front on the mouse in the airplane and the bottom of the item is exposed.  When that being said, the elements have affected the writing board as well as the backing and these is discoloration.
