Xral

Xral, 1972, by the Swedish artist (and banker) Olle Baertling outside the school, Sveavägen 65.

Olle Baertling (1911-1981) is regarded as one of Sweden’s most seminal postwar artists - and one of the few to have an international reputation. Initially inspired by the Concretists, he developed a style of his own with bright colours in triangular shapes, which, in his later works, appear to move out of the frames into the infinity of space.
