Sometimes great finds fall into your lap. Such was the case with Greg Maddux, more specifically his 1987 Fleer Update rookie card. It's the only card of any worth in the set (okay, McGwire too), and this is a perfect specimen. The 1987 Fleer set is really elegant, especially with crisp, clean corners and edges.
While I need to spend some time updating my player collection lists (I've been transitioning to Google Docs), these cards quadruple my budding Greg Maddux collection.
