Stock Photo - 23 June 2022, Brandenburg, Eisenhüttenstadt: A pair of swimming trunks from VEB Strickwaren Oberlungwitz from the 1970s, ""Carola"" bathing shoes and ""Violetta"" sunscreen spray are on display in the exhibition ""Borders of Friendship. Tourism between the GDR, CSSR and Poland"" at the Documentation Center for Everyday Culture of the GDR. The ""Iron Curtain"" ran through Europe during the Cold War, but the borders between the socialist ""friend countries"" were also a political issue and only passable to a limited extent. In the 1960s, they became somewhat more permeable, but the year 1972 marked a real breakthrough: In the GDR, CCSR and Poland, regulations came into force that allowed people to cross each other's borders without passports or visas. Millions of people took advantage of this already in the first year. They took vacation trips, day trips or shopping trips to the neighboring countries. The exhibition sheds light on the multi-layered travel experiences across the ""borders of friendship"". Photo: Patrick Pleul/dpa. - Eisenhüttenstadt/Brandenburg/Germany
