The edges of the hoarding material (5) and hoarding frame (1) are provided with cooperating magnetic strips (M1, M2), each of these magnetic strips divided into strips with different polarity (B1-B3). The polarity of the sub-strips along the edge of the hoarding will be the opposite of that for the sub-strips along the adjacent edge of the frame.
