Rocket Knight Adventures "Starring Sparkster" Very Rare Promo Trading Card (1993) - Konami from the Sega Genesis Game

This listing is for a very rare authentic promotional character card for 1993 SEGA Genesis Rocket Knight Adventures. This is an authentic card. The card was a special item giveaway to customers at very specific retailers for the Rocket Knight Adventures game on the Sega Genesis system. There were not very many of these cards sent to each store so the numbers are likely low overall. This was an authentic promo item sent directly to the retailer from Konami (the game publisher).

This pack is sealed. It has approximately 50 cards in it. It was part of the promotional items they used to give away in the retailers. I want to say software, etc.? I had a family member who used to work there, he used to give me the old crap when they didn't have a use for it. Kept this for years always liked the game. Forgot about it in a box. Now I'm trying to find a new home. Might be some marks on the corners of the cards. 

And Questions ask and I'll try to answer them.
