This card is in one of the old school type screw down slabs. The autograph is guaranteed authentic and was witnessed in person.
The old style “slab” has done a fantastic job of protecting this card. All centering looks great, the edges are sharp and the surfaces are clean and mark free.
The plastic on the screw down protector is unfortunately scraped and scuffed from doing its job for so many years.
