These have not been made for many years and it is a shame as they have the genuine look of what the story should paint.  The Sarcophagus measures 5 3/4" long x 2 1/2" wide x 2 1/4" high to the King Ornament.  If you are bidding on this, you likely know the effect.  

In brief, the King is placed in his Sarcophagus and the story tells of grave robbers that wish to relieve the treasures within.  Even though they get to the plate that warns of imminent peril if this Sarcophagus is opened, they press forward to only find the curse is now with them and the Sarcophagus is empty!   As the story continues, the King was found safely inside the Queens Sarcophagus after it had been shown empty in the beginning!  

You are bidding on what is shown in the photos only and there is no box for containment.  Condition very fine and one you should have as this is a real mystery!
