Milson Worth Ring in Orange Box: former Bill King Collection

A ring and an orange are shown. A small box is shown empty. A cord is threaded Through two holes in each side of the box and tied in the front.  The ring and orange are vanished. The cord is removed from the box and the orange is now shown to be threaded on the cord. The orange is cut open and the ring is found inside!  This was from Bill Kings Collection.   I purchased his entire MW collection before his passing.  Bill purchased all of his Milson Worth items and then placed them on display. He did not perform them.  It is very difficult to find this effect in this condition.
