Very nice framed display piece that features a game used baseball from 8-30-98, the game Mark McGwire hit home run #55. The official National League (Coleman) baseball is signed by Cardinals' hitting instructor Dave Parker with the inscription, "8-30-98 Game Used Ball Big Mac HR #55 Dave Parker". The ball is framed alongside an 8x10 photo of McGwire at the plate and an LOA from Dave Parker confirming the ball's origins. Measures 14x28".
