This is a 1990 TOPPS BLANK BACK KEN GRIFFEY JR.  I have no idea where this card came from... 

 It is REALLY NICE!

I will be listing at least 100 cards per week and have an inventory of over 1 million cards that I am going through... 

Please email with any questions you may have.

Shipping is $1.25 shipped special eBay USPS in a hard envelope.  Combined shipping is $0.25 for each additional card.
