Lennart Olausson made his gallery debut at Galleri Doktor Glas in Stockholm in 1968. The following year, he held an exhibition that drew attention in its time at the legendary Galerie Belle in Västerås.

The photorealist painter Lennart Olausson was educated at the Royal Academy of Arts (1966-1971) and at Konstfack (1961-1965). He is represented at, among others, the Moderna Museet, the National Museum and the State Council of the Arts. Moderna Museet bought its first painting by Lennart Olausson back in 1977.

The art collections at Handelsbanken Stockholm, Ericsson, Hewlett-Packard and the German Siemens include significant works by Lennart Olausson.
