Colored view of a natural tunnel in the rock, with several people in period clothing walking on a path. In the background, a lake and a snow-capped peak. Printed text at the bottom: 'Axenstrasse mit Bristenstock' and 'Eingetragene Schutzmarke'. The reverse indicates that the left side is reserved for correspondence between Switzerland, France, and England, with instructions in German and French.
