This listing is for a Vintage IBM 1999 World Book, Standard Edition Multimedia Encyclopedia CD ROM in the original box. The box has the UPC cut off probably for a rebate when it was bought. Everything in the box looks great and like it has not been used. The jewel case still has sealing tape from when it was opened as well as the top of the box. On the back of the CD ROM is the key code so it can be installed on different computers. It is from a smoke free and pet free home with one owner.
