The map "Jungfraugruppe und Aletschgletscher" designed by E. Imhof, is remarkable for its southern illumination. Today’s Orell Füssli Kartografie AG, Zürich, produced the lithography and the printing in 12 colors.
"Jungfraugruppe und Aletschgletscher" made for the "Schweizer Mittelschulatlas" from an addendum to "Die Alpen", 6th edition, by Imhof 1932.
