This was from a contest many years ago...

Approximately 20 years ago 

Found in the normal packages

These were rare and randomly placed in the package 

Fine one and you could redeem the cookie to the oreo company for a prize . 

The condition is not new...

For being as old as it is , it has been stored to save it .

Hey , if It does not sell , maybe I'll just send it in and see what happens.
