Atelier Ernst + Ursula Hiestand was formed in 1960 by Swiss designers Ernst Hiestand and Ursula Hiestand, and continued until 1981. The studio was a member of the Alliance Graphique Internationale, and in the late 60s they designed six new Swiss banknotes. Their work is inspiring.

Fridolin Müller (1926–2006) was a Swiss graphic designer, editor, and teacher who studied at The Basel School of Design. He designed the poster pictured above in 1963 for the Eidg. Schützenfest Zürich (Swiss Federal Marksman Festival). One of my favorites. Saw one in person once, it’s huge.
You can seem more of his work here, here, and here.
Last night, while looking through my copy of Neue Grafik/New Graphic Design/Graphisme actual, I discovered the wonderful work of Rosmarie Tissi. She was born in Switzerland, then studied design in Zürich, and has been a member of AGI since 1974. In 1968, she formed O&T studio with Siegfried Odermatt.
I really love how she blends the swiss style, with a more abstract style using a lot of geometric shapes. You can see more of her work here, here, here, here and here.
CCRZ is a Swiss multidiciplinary design consultancy with a great collection of work.
Some very nice work from Switzerland based studio, Bureau Collective.
Keeping with the Swissair theme, this fansite of the airline contains a ton of marketing collateral including posters, flyers and advertising. A lot of great stuff here, especially from the 60-80s.
