The invention relates to a large bill-posting installation, comprising two lateral supports with a frame which is arranged therebetween and is intended for receiving large advertisement boards. The frame can advantageously be opened in the region of the side members such that the advertisement boards can be rapidly exchanged in an extremely simple manner both from the end side and from the front and rear sides. This has the particular advantage that such advertisement boards can also be set up at inaccessible locations, e.g. close to slopes, without interfering with maintenance work which is necessary when the advertisement boards are exchanged.
