As Poland emerged from the Second World War, with heavily bomb-damaged streets lined with fences, a celebrated school of Polish graphic designers saw an opportunity for this grey expanse to become an open-air gallery. Through posters noted for their originality and surreal flair, they injected colour and hope into the world. In the 21st century, Polish graphic design innovation is alive and well, often visible on hoardings which today mask extensive urban development. Four of the best contemporary artists, Ola Jasionowska, Patrycja Longawa, Kaja Renkas, and Maja Wolna represent the breadth of today’s talent.
