Map or other informative sheet with folding, protective card covers, has square format and cover with additional protective folds and area for titling

摘要

This map folds to an approximately square format. The cover (1) has one or more additional folds (10) in comparison with the conventional covered map including concertina folding and cross folds. This provides additional protection to the folded sheets inside. In addition to the narrow printing area (8) of the spine (4), an exposed strip (11) of the rear cover at the base, provides an additional title space.
