yes,I did. those ones are my collection I bought a few month ago in Yahoo! auction .
In those days, It is said that this sticker was proof of the good ending Abe's Exoddus (ABE 99 japan version)that players carried out .
Stickers were presented to the first hundreds arrivals by the Japanese video game Publisher(
Riverhill Soft),after players sent an application form be accompanied by the game with a photograph of the good ending scene that they took .
And this Keychain is one of
4 different types of ones for ABE a GOGO's bonus items.
