As 'usual', she was greated by Pagart (Polish Art Agency). She wore beige coat and (it seems) floral print headscarf. Marlene went to the Bristol Hotel (the one in which she stayed back in 1964).
The plan was to give 13 concerts (6 in Warsaw, 5 in Gdańsk and 2 in Wrocław), then get back to Paris to get some rest as her health was really bad those days: in her journal she was writing about insomnia, back pain and frequent bleedings. Despite this, she gave all 13 concerts and didn't stop rehearsing with the orchestra.
You can watch the airport arrival and Marlene during concert in 1966 in Warsaw here...:
...and something from a fan's private collection, including Polish magazine covers from 60s here(I hope you can watch this one).
She traveled by plane and train from town to town. Even though most of the organisors were able to provide decent conditions, in Gdańsk there were some problems; she didn't quite like the Grand Hotel in nearby Sopot, the stage location wasn't good either: she sang in shipyard which was just next to the railway; trains were so loud they interrupted the songs. You can find photos from Gdańsk airport right here. This Chanel (?) suit suited her so well. :)
Big highlights from Dietrich's second visit to Poland were her meetings with Polish artist: musicians (you can see beautiful Marlene with two well known pianist here), actors, among which the most important person was Cybulski. She met him in Wrocław, when she was staying in Monopol hotel, where eventually Cybulski also decided to spend some time. They got along immediately; she knew his movies; they spend quite a lot time together and when it was high time for her to get back to Warsaw, he escorted her to the railway station. Afterwars, they started to exchange letters.
After concerts in Warsaw and a glass of wine drank with musicians, Marlene headed for airport. She declared she wanted to return to Poland once more...but unfortunatelly, it has never happened.
