Abstract: A continuous strip of mutually adjacent information-bearing panels are joined together by hinge means, each of which comprises a series of hinge openings and hinge sections. The relative positions of the hinge sections and openings of one hinge means are so positioned in relation to the hinge sections and openings of a further hinge means as to enable the strip to be folded in a bundle or part bundle form, so that a selected panel can be brought to the top of the bundle or part bundle, with the hinge sections of a respective hinge means lying within the confines of the openings of the remaining hinge means.
