"Illustrations of the Glacier Systems of the Alps and of Glacial Phenomena in General…", Johnston, W. & A.K.

This interesting sheet contains 6 maps and diagrams depicting Alpine glacier systems including Mont Blanc and Chamonix in France and the Bernese Oberland in Switzerland.

Keith Johnson worked in conjunction with German Heinrich Berghaus to produce the Physical Atlas, the first truly comprehensive thematic atlas. The maps from this atlas made a huge impact on cartography in general and specifically on the graphic portrayal of geographical data.

This example has the small stamp of the Wakefield Mechanics Institution. Established during the Industrial Revolution, the Mechanics Institution movement in Britain intended to provide adult education for the working man. At a time when most libraries were available only to subscribers, the Mechanics Institutions frequently became the libraries of the working class. Formed in 1841, the Wakefield Mechanics Institution was dissolved in 1935 and its library dispersed.
