<p>A device (1) for displaying a graphic between two cover sheets. The device (1) comprises: a holder (2), a first protective sheet (3), and a second protective sheet (4). The holder (2) has an elongated slot (7) and at least one aperture (8, 9) to receive at least one wedge (5, 6). The thin sheets (3, 4) are positioned within the slot (7) and each has a cooperative protrusion (10, 25) that extends into the apertures (8, 9). These panels are held in place by the wedges (5, 6), which are positioned between the protrusions (10, 25) and may have interlocking projections (22) that fit into notches (21) on the protrusions. The sheets may be made of a resilient transparent polymer. The holder may be mounted onto a screw member (16) fixed to a lower clamping portion and is able to rotate.</p> |
