  conserve the natural beauty of and the investment of the state in  state
  parks  and  parkways  by preserving and regulating them for public uses,
  for the resort of the public for recreation,  transportation,  pleasure,
  air,  light  and enjoyment by keeping them in good order for the welfare
  of society, and to prevent the unrestricted use of signs and advertising
  structures and devices immediately adjacent to  them,  no  person  shall
  erect  or  maintain  within five hundred feet of the border of any state
  park or parkway  any  advertising  sign  or  advertising  structures  or
  devices  of  any  kind,  except  under written permit from the office or
  state agency charged with responsibility for  the  maintenance  of  such
  park or parkway. The provisions of this section shall not apply to signs
  erected  or  maintained  upon  property  in  connection  with a business

  than twenty-four square feet, do not extend more than fifteen feet above
  the ground level, and are placed on the fronts of buildings.
    2.  The  provisions  of  this  section  shall  apply  to  all parkways
  constructed within the limits of a city  with  state  funds  or  federal
  highway  aid.  In the event that jurisdiction is transferred pursuant to
  law from the office or state agency to a municipal  park  commission  or
  department,  the provisions of this section shall remain effective as to
  such parkways, and shall  thereafter  be  enforced  by  the  local  park
  commissioner, commission or public authority to whom the jurisdiction is
  transferred.
