    • A trading card includes a front wall, a back wall, a bottom wall, and a top wall. The front wall retains a viewing lens. The back wall retains an image. The bottom wall extends between the front wall and the back wall. The top wall extends between the front wall and the back wall. Three of the walls are moveable relative to the other wall to move the trading card from a folded configuration to an unfolded configuration. In the folded configuration, the walls are substantially parallel to each other. Further, in the unfolded configuration, the front wall and the back wall are substantially parallel and spaced apart, and the bottom wall and the top wall are substantially parallel and spaced apart. Additionally, the image is viewable through the viewing lens when the trading card is in the unfolded configuration. Moreover, the image can be on a piece of film and the viewing lens can be a magnifying lens. With this design, the trading card can be sized and shaped like a regular trading card when the trading card is in the folded configuration and the trading card can be simply expanded from the folded configuration to the unfolded configuration in which the trading card functions as a magnifying viewing box.
