Abstract
A novel card device which may be supported on a refrigerator or other metallic objects by magnetic coupling thereto. The card device is preferably made in the form of a mailable postcard or otherwise a greeting card or an announcement card. In the case of an announcement card and postcard, a single substrate is employed and a magnetic film is adhesively secured to an upper face of the substrate. A second substrate or otherwise a portion of the first substrate may be folded over and placed facewise upon the second substrate and adhesively secured thereto. The magnetic film is thereby captured between the two plies. In the preparation of a greeting card, a substrate may be folded into three different panels with one panel being folded over the next adjacent panel and attached thereto with a magnetic film secured therebetween, again usually by adhesives. A message may be then presented on any of the exposed faces of the panels. In addition, individual strips of the magnetic film may be employed.
