These are the earliest versions of the J-Storm Urban Maps available. They are also the smallest - great for decorating a cubicle or to arrange in a grid.
Four of these in a 2x2 grid is the same size as a 14" map.
Nine of these in a 3x3 grid is the same size as a 22" map.
Five of these, plus one 14" map is the same size as a 22" map.
