This is a vintage 1965 Milton Bradley - Addams Family Mystery Jigsaw Puzzle - Cleopatra's Plight 

The size of the puzzle is 14" x 24 1/8" and has around 600 pieces. The box is still in very good condition.

This MYSTERY puzzle includes a story booklet to set up a mystery scenario (what's wrong with Morticia's plant Cleopatra?), which the assembled puzzle provides clues to solve. Once the puzzle is finished and the clues are understood, the back of the booklet confirms the solution to the mystery.

The booklet has the pages with the answer sealed together and says "do not cut open" This was followed and the paper is still intact/sealed.
