This Friday, 7 June (2019) sees the start of the 33rd Ljubljana Biennial of Graphic Arts, which runs until 29 September. This edition is curated by the art collective Slavs and Tatars and is going out under the title Crack Up - Crack Down, with a focus on satire in the region. The Biennial takes place at the International Centre of Graphic Arts (Mednarodni grafični likovni center, MGLC), in Tivoli Mansion, the building shown in the image at the top of this story. To mark the event, which has been running since 1955, we thus went to the archive (aka Wikimedia) and returned with these images of the Mansion, and other parts of the park, in first half of the 20th century.
