The application for a taxicab driver's license shall be made in writing by the applicant upon forms to be furnished by the Manager, which must be completed in full. The application shall be accompanied by two (2) unmounted, unretouched photographs of the applicant taken within one hundred days of the date of the application and which shall not be less than 2x3 inches in size and suitable for the attachment to such license. If said license is issued to said applicant, one photograph shall be securely attached to the license issued to said person and the other shall be filed with the application in the office of the Manager. Each licensed operator shall at all times display said license and photograph in the taxicab so that any passenger or passengers occupying the taxicab may readily observe same.
