This is a 1989 Donruss baseball card featuring Mark McGwire of the Oakland Athletics, card number 100. The card showcases McGwire in his iconic yellow and white uniform, with a circular team logo in the upper right corner. The card appears to be in well-loved condition, exhibiting visible signs of edge and corner wear throughout the borders. As a prominent slugger from the late 1980s, this card is a classic representation of the era's hobby-staple Donruss sets.
