Room Service by Don Wayne and David Copperfield

As performed by David Copperfield in a early special.  This is complete with everything included.  A key and attached key tag are shown and placed in a visible location for all to see.  Three people each pick pick a randomly selected three digit number by selecting a one to 9 number.  When the key is removed it is seen to contain the three digit room number selected. Now very collectibles and scarce.
