Retroavangarda is a non-profit project that involves online promotion of artists from all over the world and organizing real life exhibitions. Retroavangarda Facebook fanpage is one of the leaders on the subject of international contemporary art and has nearly 90 000 fans. As a part of Retroavangarda project, Anna Kłos has recently organized a number of international exhibitions of which she was the curator, i.e. Post-Ecuador Poster Bienal, International Collage Exhibition, exhibition of contemporary Peruvian art and more. At first, the exhibitions were held in renowned, befriended galleries, but since April 2018 Retroavangarda has its own gallery space in Jerozolimskie Business Park – a modern office complex in the centre of Warsaw, placing itself at the same time in the worldwide trend of promoting good contemporary art in attractive public spaces.
