Circa 1998 Nike NK 850 Geo Serie A SSC Napoli Official Match Ball.  Please see pictures as ball does have markings, signs of use, fading and wear due to age and use. Ball is currently about 90% full of air.  I haven't tried to add any additional air but it appears to be holding in its current state.  Please see pictures as there is a scratch next to the air hole.
