The beauty of the oil

Oil has made it possible to live in a level of prosperity that no one would ever have thought possible. A monument to this era are the brutalist highway bridges, which since the 1960s have made it as easy as possible to get from A to B.

The golden age of the petroleum-based society

One day, this era will come to an end. The last barrel of oil will be opened. Just as the steam turbine replaced horsepower, renewable energies will replace petroleum. People will be able to marvel at the beautiful combustion engines in the transport museum. Humanity's next transition from one energy source to another is imminent and unstoppable. With everything that goes with a transformation.

The melancholy of the past and the joy of what may come are irrevocably linked in every transformation. And so I do not want to condemn the manifested monuments of this era and welcome the new.

The most important Bridge of the swiss capital

Bern has many beautiful bridges. But the most important bridge in Bern leads a shadowy existence: the Felsenau Viaduct. Without this bridge, the A1 freeway would be cut in half.

In the shadow of the Aare trench at a height of 60 meters, this brutalist structure is often overlooked in favor of such beauties as the Kirchenfeld Bridge. Yet, concrete also has its charm.

FAQ Products & Shipping

Your order (provided it is a poster) will be shipped unframed in a sturdy cardboard tube.

If you have ordered a mounted F4 poster, it will be delivered to you directly by the Bernese printing company Uldry (this service is only available within Switzerland).

No, I ship my posters without picture frames. However, there are providers with great products that I can recommend.

In my opinion, the most beautiful and simplest frames are so-called "Halbe Rahmen" (half-frames). These feature a unique mounting principle using magnetic frames. This allows the pictures to be framed effortlessly without any tools or annoying clips.

Metal Picture Frames

Wooden Picture Frames

With these frames, the formats are cut flush to the poster size. However, it can also look great to choose a larger frame to give the motif more breathing room with a passe-partout (mat board). Real glass can be used for the smaller A2 and A1 formats. For the large F4 world format, I recommend only using Plexiglas for safety reasons.

Please keep in mind: When dealing with graphic prints on paper, you are looking at a natural product, and tolerances can be +/- 5 mm depending on the size.

I offer all poster sizes, from the smallest poster format A3 to the world format ("Weltformat") F4. Here is an overview with the most important information:

A3 – The small one (29.7 x 42 cm) 
As large as a double A4 sheet. Suitable for cozy niches, smaller rooms, or narrow hallways where the motif can be viewed from up close.

A2 – The small large one (42 x 59.4 cm) 
A classic "small poster", as large as a double A3 sheet. This format is frequently seen in Swiss cities for wild postering. It is ideally suited for rooms that have something to say – for the kids' room, the office, or as an eye-catcher in the kitchen.

A1 – The large small one (59.4 x 84.1 cm) 
A proper poster. This one isn't really that small anymore. It fits perfectly above the sofa in the living room, next to the dining table, in a practice/office space, or in a spacious entrance hall.

F4 – World format / Weltformat (89.5 x 128 cm)
The flagship for your wall design. The exact same size as the APG street billboards used in Swiss outdoor advertising. An absolute eye-catcher for really large spaces, wide lofts, or minimally furnished rooms.

Since picture frames in the F4 world format are hardly available in regular retail stores, I offer my F4 posters ready-mounted.

The posters are securely mounted onto a sturdy aluminum Dibond (Alu-Dibond) panel. Two U-profiles are pre-installed on the back, making it incredibly easy for you to hang it up using just two nails or screws.

This service is handled by my partner printing company Uldry in Hinterkappelen (Bern) and is delivered directly to your home in the highest quality.

Please note: Due to their size, mounted F4 posters are only delivered within Switzerland.
