When Switzerland became a travel destination in the 18th century, the foundations were laid for tourism to blossom. That was accompanied by a new kind of image production, one that served to preserve travel memories. In the 1760s, the landscape painter, illustrator and engraver Johann Ludwig Aberli (1723-1786) invented the hand-coloured outline etching, a mixture of print and watercolour. The process became known as the «Aberli Style» and was subsequently emulated by artists such as Heinrich Rieter (1751-1818), who advanced the technique. The prints were expensive souvenirs that were distributed widely across Europe as they fostered the image of the European Arcadia, Switzerland. The Foundation (Stiftung) Familie Fehlmann owns a fascinating collection of these prints in the «Aberli Style». The prints are now on public display for the first time to mark the 100th anniversary of the birth of Heinz Fehlmann-Sommers (1919-2015).
