ABSTRACT:
A marker device suitable for attachment to a video cassette or the like is disclosed, which marker device comprises an elongate laminar device having first and second faces on opposite sides of the device, the first face of which is adapted to be secured to a surface of, for example, a video cassette; and the second face of which includes a window through which indicia marked upon the device may be viewed; and, between said first and second faces, an arrangement of the type in which a first foil layer can be releasably attached to a second layer, points of attachment therebetween being visually distinctive and constituting said indicia; and means for separating said first and second layers so as to release said points of attachment and thereby erase said indicia. In another embodiment, the marker device comprises an elongate laminar device having opposed first and second faces, the first face of which comprises a peel-off protective strip covering an adhesive surface; and the second face of which includes two strips of material the ends of which are secured within the device and which when the materials are pressed together generate an image at the points of contact, and a cursor having a bar located between said strips and being slidable along the length of the device between the respective ends of said strips, and wherein said image can be erased by traversing said bar over the region where the image is located.
