All retail pharmacies shall identify their location by an interior or exterior sign that identifies the establishment as a pharmacy through the word or words "pharmacy," "druggist," "drugs," "drug store," "Rx," "apothecary," or the like. The pharmacy may display the sign upon issuance of the pharmacy's license by the board. The sign must be immediately removed or covered upon the nonrenewal, surrender or revocation of the establishment's license, or upon the permanent closing of the pharmacy.
