A mountable display for a temporary vehicle tag is provided. The display includes a transparent envelope adapted to receive a paper tag overlayed upon a reinforcement board or card. The envelope may have an adhesively coated flap extending from an open end thereof, the flap being adapted to pass around the envelope and seal to the back thereof, such that the temporary tag is received and maintained in a transparent sealed envelope. Screws or bolts pass through the envelope and through designated areas of the reinforced tag, for securing engagement with an insert received by a panel of the vehicle. The bolts or screws make securing engagement of the envelope and tag to the vehicle by sandwiching the combination of the envelope and reinforced tag between the head of the bolt or screw and the vehicle panel.
