Giant inflatable elephants - the unofficial mascots of the festival - rule the city center under Ještěd every two years, when the Mateřinka Festival takes place in Liberec for several days. Another crucial part of the festival is the opening parade of masks and costumes from the Naive Theatre collection. The main part for the audience and visitors is waiting at many of the venues of this unique festival, focusing on professional puppet theatres and their productions for pre-school children. Photos of Josef Ptáček from the particular years of the Mateřinka Festival can be found below on this page.
