The 2016 Swiss panoramic stamps "Lake Constance" does not depict a real landscape panorama, it is an artists rendition and a compilation based of three landscape photographs taken at different locations of the lake.
The left stamp is titled "Mt. Säntis & Romanshorn", showing the Alpstein Range with its highest summit, the Mt. Säntis. The second stamp is titled "Obersee", it shows in distance the Alpstein Range again and the third stamp is titled "Untersee & Ermatingen" and depicts a view from the lake towards the village Ermatingen.
The stamps were designed by Wemako Kommunikation in Ermatingen.
