Museum Piece is a mission given to Niko Bellic by Ray Boccino in Grand Theft Auto IV. In this mission, Ray wants Niko to sell the load of diamonds they obtained in the earlier mission to a buyer at a deal in a museum. Johnny Klebitz will be there as well with Niko to provide support and take his cut of $1 million back to The Lost MC. However, the deal goes horribly wrong upon an interruption.
