The collection reflects the activity of the architect Gheorghe Leahu, known in Romania for his watercolours representing streets and monuments of Bucharest destroyed as a result of the “urban systematisation” policy of Ceauşescu’s regime. The Gheorghe Leahu Collection includes watercolours, drawings, manuscripts, letters, photographs, and books.
The informal group of the Six Artists consisted of Raša Todosijević, Era Milivojević, Marina Abramović, Zoran Popović, Neša Paripović and Gergelj Urkom. The work of these artists began with the establishment of the Student Cultural Center in Belgrade in 1971. It lasted to 1973, when each of them started working independently. Their artistic activity was above all a resistance to the existing practice that was being taught in the framework of school programs at the Academy of Fine Arts in Belgrade. They advocated the establishment of a modern approach to the reconstruction and functioning of artistic institutions, as well as to redefining the effects of art. The accent started to be set on the artist as a subject and to his authorial speech, "speech in the first place". The artists began to introduce new media into art (installation, bodybuilding, photography, film, text ...).
