We ponder the question: What truly defines a sports card? We analyze a range of factors like material composition, size variations, and unique shapes that challenge the traditional notion of what constitutes a card. We question whether items like newspaper inserts, thick box cards, or even three-dimensional cubes can be considered cards. Furthermore, we explore the influence of intentionality, discussing whether an item's intended purpose as a collectible or its inclusion in a sports card set contributes to its classification. We acknowledge the complexities and blurred boundaries within the realm of sports cards.
