A flexible decorative display device for attachment to a hitch receiver. The flexible display device is formed from a bendable sheet having a distal front surface, a proximal rear surface, an outer shaped outline, and interior shaped edges. The interior shaped edges form both a central opening to accommodate the trailer hitch receiver and a tongue. The tongue has tongue alignment cavity edges that define an interior tongue pin-receiving cavity. The tongue bends backwardly at a flexure line to fold back over the outside of the receiver tube, aligning the tongue pin-receiving cavity with the pin-receiving hole of the receiver.
