ABSTRACT:
A map is segmented into columns and rows, and pairs of segments are lamind back to back in a particular manner: the segments of each column serially, and the columns serially. A marginal flap is provided at the top of each segment, wider than the segment and with a slot in it as well as the segment. A ring passes through the slots to hold the segments together, and to permit the viewing of two segments which are adjacent in the map.
