Originally issued as an educational aid, Yaggy's charts are among the most distinctive and stunning comparative charts ever published. Unlike the smaller, simpler and more analytical comparative charts found in atlases, Yaggy's images present a living landscape set with an exaggerated scale which gives each a strange and other-worldly appearance. In the Ascending Regions the major mountain peaks from all continents (except Antarctica) are represented. Small mountaineering figures are used to indicate important ascents with the date and explorer's name including Humboldt (1802), Boussingault and Hall (1831) and Gerard's climb of Hindu Koh in 1818. Of special interest is the depiction of the balloon ascents of Gay Lussac and Green. Volcanoes are shown with fire, smoke and magma flows. The lower elevations fill the foreground with the elevation given from major cities including Denver, with the vegetation and local crops.
Yaggy's views are exquisite and scarce examples of multi-stone lithography with each stone carrying a different color ink to build up the image to a complex, beautiful image. We count at least six different colors and perhaps as many as eight.
