(57) The sign 10 of the present invention has a drop-down cassette 12 that can be worked
on single handed at ground level with speed, safety and efficiency where in its elevated
position the cassette 12 is housed behind convexly curved Polycarbonate panels 13
which allow display of posters loaded onto the cassette 12. The sign 10 removes the
principal problem attached to prior known form of high level advertising, namely,
the difficulty of access without costly special equipment to change advertising posters
and to maintain and repair all working electrical parts.
