A nice double-hemisphere world map showing rivers, topography and a few place names. A small portion of Antarctica is delineated and named South Shetland. There are four spheres surrounding the map depicting the meridians, parallels, zones and circles. A scale at left depicts the relative heights of mountains around the world. Engraved by E. Huntington.
A nice impression on a bright sheet with archival repairs to a centerfold separation in bottom blank margin and a 2.5" tear at left.
