This 1990 Donruss Nolan Ryan #659 is a must-have for any Baseball card collector. The card features pitching HOF legend Nolan Ryan in his Texas Rangers uniform and is certified by PSA with a grade of 9 (MINT).
I am also the original and ONLY owner of this card from the mid 80's so I'm selling it from my personal collection.
