Concave Face is a work of art by Hilde Mæhlum, who is recognized for her unique masks. The work explores the concave face shape and optical phenomena, and uses a variety of materials, including paper, metal and stone. Mæhlum focuses on how the viewer's consciousness and emotional state are affected by the artwork, which gives a deeper experience of the art.
The artwork is inspired by quotes from "The Little Prince" by Antoine de Saint-Exupéry, adding a literary dimension to the visual experience. In addition to the artwork itself, tours and sculpture walks are offered in Ekebergparken, where visitors can take part in interactive experiences such as light walks and fog walks. This provides an opportunity to experience art in interaction with nature and the surroundings.
