摘要：
The present invention relates to ordinary poster boards, in particular those known as large poster boards.
The purpose of the invention is to simplify the changing of messages. It is also the intention to make it possible to convert existing large poster boards easily and cheaply into boards according to the invention.
The use of extensible plastic film over the board surface is known.
What chiefly characterises the invention is the design of the board frames where they are attached to the board so that they cover all the outer areas of the poster board surface, that each frame contains a rail (9, 12) one long edge (10, 13) of which is displaceable inward/outward to/from the board surface, that the plastic film (7) on one side has a strip (8) against which the long edge of the rail can act and press the strip against the surface of the board. When applying the film, the strip (8) is pressed towards the edge of the board with a tool (10) that gets support from the outer edge (23) of the frame.
