From the wind-scoured summit platform of Pilatus-Kulm at 2,132 meters, a railed stone pathway clings to the cliff face while an ocean of snow-capped Bernese Alps — Eiger, Mönch, and Jungfrau visible on the horizon — fills the frame in this breathtaking early real-photo postcard from Lucerne publisher Globetrotter A.G. The sheer verticality of the foreground rock against the sweeping panorama of the Reuss valley below makes this one of the more dramatic alpine viewpoints in the Swiss postcard canon, a peak accessible since 1889 via the world's steepest cogwheel railway.
