Such notice shall include an application blank for registration and shall specify the amount of license fees due and the registration period covered by such license. Application blanks shall also be furnished all branch offices of the department of revenue and license fee offices designated by the director of revenue under the provisions of section 136.055 where they shall be made available to any person upon request.
