Softcover. Near Fine. Four-panel folding lithograph brochure, 18 x 44 cm when unfolded, undated but c. 1920s. One side entirely a color lithograph view of hikers overlooking Aletsch Glacier (the largest glacier in the Alps) from 11480 feet on Jungfraujoch, with other peaks identified in the background. The other side has two single-panel mountain views (comprising the front and rear panels of the folded brochure) and a sketch map showing the route of the Jungfrau Railway, as well as brief text in English, French, and German. The Railway, constructed between 1898 and 1912, runs from Kleine Scheidegg to the highest railway station in Europe at Jungfraujoch, almost entirely in tunnels cut through the rock of the Eiger and Monch. The lithographs are by Emil Cardinaux (1877-1936), a pioneering Swiss graphic artist known for his travel posters.
