Gray's New Map of the World In Hemispheres, With the Comparative Heights of the Principal Mountains, and Lengths of the Principal Rivers of the Globe

Descripción:

Map. Hand colored engraving. Sheet measures 17" x 27 1/4" Fascinating double hemisphere map surrounded by infographics showing comparative rivers, mountains, and local times. The maps are highly detailed, with countries, regions, major cities, rivers, and topography labeled. In the upper corners, the world's rivers are unfurled and laid out in order of total length, creating a triangular shape that is mirrored on the bottom half of the chart by an arrangement of the world's mountains. Divided by continent and hemisphere, the mountains are arranged from smallest to tallest, with peaks and heights labeled. Mountains of the United States, of lower elevations than global mountain ranges, are included along the center bottom. In the top center, a time diagram that appears as a clock shows estimations of local time of the fifty principal cities of the world. The map is in very good condition with minor wear to centerfold. Ormando W. Gray was a map publisher active in the later half of the 19th century. A civilian engineer and surveyor, he worked with several other map publishers like Henry Walling and Colton. His state and county atlases are well known. Frank A. Gray, presumably a relative, produced many maps that were published by the family firm, O.W. Gray & Sons. N° de ref. del artículo 328201
