The World Of Elvis Presley NZ Edition Phone Card Set Collectable.

Bought about 30 years ago for $500, and has been in its original packaging all that time. The phone cards had real value. They could have been used to make calls. What I don't know is whether they would still be valid after all this time. It would, of course, ruin the collectable, but just someting I had forgotten to add. Sold one already. But have another. Identical, except for the number.
