The invention relates to a display frame (1 ) for graphic advertising material that is suited for use with a pricing system. The frame (1 ) has a flat body (2) which is traversed by parallel lipped channels (29) that releasably receive inserts (30). The frame (1 ) is moulded from plastics material with webs of the channels (29) provided by connectors (22). The inserts (30) are configured to display pricing in a manner that allows variation and these allow for pricing changes to be made while the same graphic material is maintained on the display frame (1 ). The graphic material may also be provided by inserts (30) and removably secured in the channels (29). In a preferred embodiment, the frame (1 ) has movable clamping-rails (7) along outer edges. The clamping-rails (7) are resiliently biased into a closed condition by clips (12) with resiliently deformable cam formations to retain a suitably sized poster and/or transparent screen against the front side of the frame (1 ). The clamping-rails (7) and clips (12) for biasing the clamping-rails (7) are also moulded from plastics material. |
