The exhibition project was inspired by the historical exhibition of the works of the German graphic artist, sculptor and painter Käthe Kollwitz, which took place in the Zachęta Central Bureau of Art Exhibitions (CBWA) in 1951. The development of documentation and analysis of the exhibition reception was possible thanks to a research project conducted in recent years at the Zachęta gallery, in which exhibitions, rather than individual works, were the subject of research.

"Simple Rainbow" was created in 1991 for the exhibition entitled "Epitaph and Seven Spaces", curated by Janusz Bogucki and Nina Smolarz. The rainbow stood on Małachowskiego Square until 1993. After 28 years, it will reappear on the square, as a conversation starter on today’s society and world.

Flight, a sculpture by Roman Stańczak, will be presented at the Polish Pavilion during the 58th International Art Exhibition — La Biennale di Venezia. Visitors will experience the unique form and scale of the sculpture — an inside-out aircraft — but also the effect of an unexpected “reversal of the world”. The project delivers a commentary on the situation of political and economic transformations.
