The invention relates to a display frame for graphic advertising material that is suited for use with a pricing system. The frame has a flat body which is traversed by parallel lipped channels that releasably receive inserts. The frame is moulded from plastics material with webs of the channels provided by connectors. The inserts 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. The graphic material may also be provided by inserts and removably secured in the channels. In a preferred embodiment, the frame has movable clamping-rails along outer edges. The clamping-rails are resiliently biased into a closed condition by clips with resiliently deformable cam formations to retain a suitably sized poster and/or transparent screen against the front side of the frame. The clamping-rails and clips for biasing the rails are also moulded from plastics material.

An illuminable sign includes comprising a translucent panel having an engraved message and an electrically powered light source oriented to direct light into an edge of the translucent panel. A remote may be used to transmit a wireless signal to the illuminable sign when a button on the remote is pressed by a user. The illuminable sign includes a wireless receiver that receives the wireless signal and turns the light source on and off in response to the wireless signal. Accordingly, the user may selectively illuminate the sign and express the message to another person, such as a driver in an adjacent automobile. The illuminable sign may be securable to the inside of an automobile window using suction cups in a manner that the engraved message is directed to be viewed through the window.

A placard with an image may be placed upon a rod such that a passenger of a vehicle may imagine interactions of the image with the changing surroundings of the vehicle. Ideally, the placard should be clear except of the image which may then appear on both sides of the placard. A hinged suction cup connection to the placard allows for reversibility of the placard and or the placard to continue being held on the window when in use. A tether may also be utilized to secure the placard to the rod.
