@Weasel: no. On the paper-sheets was only something written about the history of the Syrena, about the model, not this specific car.

It was not a bit dusty, it was real dusty in Saturday. It hasn't rained there since a while, it was sunny summer weather, and several thousand of cars (minimum 3000 classic cars) and several thousands of visitors (over 20.000 in 2012, this year even more) have caused a lot of dust.
When I left in the evening, I had to rinse off the windscreen.
