Informative card made of sheet metal

摘要

An informative card, such as a baseball trading card, has a rectangular shape and is made of a single thin sheet of metal in such a way that it is free of pointed corners or exposed raw edges. The informative card has four rounded corners and a double-thickness frame defined by a folded lip which has four straight edges and four rounded connectors joining the straight edges at the corners. The folded lip provides an unbroken radiused peripheral edge bordering the card. A central display panel of the card is offset rearwardly to form a raised ledge on the front side of the card surrounding the central display panel.
