    Abstract: A paper foldable map which includes a cover, a map portion, paper reinforcing and a present location indicator with the marker. The cover is a single combined body which includes a front cover side and a back cover side. The paper reinforcing is of an appropriate width and is provided transversely along a center line of the map. The map portion itself is folded in a specific way. First, with the paper reinforcer as the center line and with an appropriate number of cuts made in the upper and lower portions of the map portion, the map portion is folded towards the paper reinforcer by following the steps of inward folding and outward folding with an equal width one after another. Then, the map portion is further folded from its right and left sides opened. An appropriate portion of the back side of the folded map portion is bonded to one side of the cover. The present location indicator provided with the marker fits over both sides of the cover in a manner to be freely slidable in the vertical direction.
