ABSTRACT:
A two-layer map device for any given area has a first, base layer and a second, upper layer superimposed and secured by a pressure-sensitive adhesive layer. The upper layer is articulated into the primary areas of the map, so that individual states, or the like, can be peeled off, one by one, in any desired sequence, to reveal the corresponding, individual states, or the like, of a map on the under layer. The upper layer may be neutrally colored, and opaque, to cover a bright, multi-colored map on the lower layer, underneath, so that as an articulated element of the upper layer map is peeled off, a multi-colored picture of the same state or district will appear underneath. This provides a means for displaying the states or districts in sequence, to record travel, for example.
