The Swiss postal service (formerly known as PTT), today operates internationally under the name "Swiss Post". In Switzerland, the company uses three different names: "Die Post" (in German), "La Poste" (in French) and "La Posta" (in Italian and Romantsch).
This Martin Altenburger & Adrian Frutiger-designed logo incorporated the Swiss cross.
This logo (using the typeface Frutiger) was introduced when the PTT was split into two separate companies: Swiss Post and Swisscom. This design still featured the PTT brand, but only as an intermediary solution.
In 1998, the PTT name was finally removed from the logo, & the cross became slanted.
In 2009 the logo was slightly altered, now using a customised version of the Frutiger typeface.
