For 2023 the Swiss Post Office launched a concrete wall stamp printed with cement pigments in an ultra-matt finish for tactile effect. The only thing more Swiss is the stamp’s entire product description, which details how this stamp aligns with the three pillars of Swiss Post’s art support policy [revised in 2020], and how that policy aligns in turn with Swiss Post’s ongoing policies for supporting the arts.
In 2021, to announce this newly updated art policy, and to draw attention to Swiss Post’s art collection and architecture, Swiss Post introduced a blank canvas stamp. It is sold out, but when augmented by a CHF0.10 stamp, is still valid for use. The making-of video is as sublimely boring as one could hope; it must have been a great source of comfort in the midst of pandemic uncertainty.
The concrete stamp is available in single, 4-, or 8-stamp sheets. [post.ch, thanks Bruno]
