ABSTRACT:
An informative card, such as a baseball trading card, has a rectangular shape and is made of sheet metal in such a way that it is free of pointed corners or exposed raw edges. The informative card comprises a single-layer metal blank which has a burr in the form of an upstanding pointed ridge along the periphery of the blank. A protective film, such as a layer of varnish, is applied on the card to cover the side with the burr so that the burr is shielded.
