It features paintings he created in the period 1953–1975, a time during which he found his artistic voice in painting and printmaking alike. His works depict lyrically inspired, rhythmically repeated and enigmatic images of humans, particularly female nudes and male portraits, furniture and everyday objects, which come to life in an endless, indefinable space.

From landscapes to landscapes and to the sky
In remote, timeless spaces nested in stars and interstellar expanses people have been creating parallel worlds where life is usually ideal and radically different from the one they’ve been living themselves. Artists are no exception…as shown in the exhibited works of the painter Marko Šuštaršič. They reveal constellations of forgotten thoughts, actions and people whose existence hinges on snapshots of humans and ornamental signs frozen in time, waiting in typical lines. Persons, objects and fragments of ornaments coalesce into Šuštaršič’s abstract signs resembling outer space, but he creates them with imaginary links between individual lines.
The exhibition in Bežigrad Gallery features his paintings from the period 1953–1975. The painting called Interior in the Exterior (1956) says everything about the painter's artistic explorations and interests in the mid-1950s just with the title. It is an important piece of work because of the shift from an interior space, a room, to a landscape and a firmament, and because of the dynamics and positions of the pieces of furniture, which seem to about to move into the exterior.
His paintings and prints from the period 1962–1966 in particular typically feature compositions or combinations of compositions and rows of certain shapes. All the paintings and prints seem like constellations of thought. They are designed to depict infinity, which may be concrete, like the sky. Šuštaršič had already displaced and sorted out everything in spaceless and timeless dimensions in his earliest paintings and prints.
