EXTREMELY RARE / ONE-OF-A-KIND CARD?? Note: I have not been able to find another Pokémon card quite like this. The Grey Stamp can be seen VIVIDLY and very CLEARLY displaying "1st Edition" in a definite Grey color. There is some visual damage to the back of this card. (Scratches along the top sides of the back of card).
