The maps are quite accurate; however, the antique ones gave us sometimes trouble indicating our proposed route. We tried to be as accurate as possible but sometimes we cheated a bit if the exact route on these maps would suggest we planned to visit India or Tibet (Mongolia is tricky with that respect).
Another lovely thing on some of the elder maps is that decorations (such as blowing faces for wind directions) may take more space on the map than the maps themselves! Note that the publishing dates of the antique maps indicated below may be approximate; besides, some of the maps have been published several times, but in the end they're all different.
