While this is not the original version, it is sealed
 
You show three black phonograph records to the audience. The first black record is placed into a record sleeve and a colored silk is pushed through the record hole. When you remove the record from the sleeve, it has magically changed its color to that of the silk.
 
This is repeated with the other two records. Nothing is found when you open the sleeve to show the inside. 
 
We do not believe English instructions are included, usually it will note they are available on the outer package, this one does not mention that.
