  • Sign holder
    Patent number: 4753027
    Abstract: A sign holder having a substantially transparent, flexible cover which is closely received in a base. The cover is removed from the base by flexing the cover to free the ends of the cover from pockets on the base. The sign is positioned between a mounting surface of the base and the cover. Air channels are provided in the base and the walls forming the pockets to prevent the formation of a vacuum when water enters the interface between the cover and the base, while inhibiting external access by vandals.
