This was said to be a mid 1980s Japan made Airwolf Promo Phonecard and Postcard Set.
Issued in 1985 to promote Airwolf`s airing on Japanese TV.
You got the card itself with a picture of Stringfellow Hawk A.K.A Jan Michael Vincent on the front.
The card is placed in a two fold Airwolf postcard.
Update:
We have been informed that this is fake merchandise and is really a Rail Card that the user can add their own picture to it. Orange cards 500 are magnetic pre-paid cards that can be used by Japan Railways companies. Special thanks to Shingo Takeda for the updated information.
