The map displays lines of latitude. What is the approximate range of latitudes shown on this map projection, considering the visible curvature and grid lines?

The visible grid lines suggest that the map extends from the equator (0°) to the polar regions. The lines of latitude are shown curving towards the poles, and the presence of what appears to be the Arctic region (around point 3) indicates coverage up to high latitudes, likely around 80° to 90° North. Similarly, the southern extent shows parts of South America, suggesting coverage down to mid-latitudes in the Southern Hemisphere.
