We all know that Americans love to display their flag. Also in these challenges the entries with the American flag can be found in the most disparate topics.
Europeans when confronted with this attitude experience a sense of wonder. In fact, it is difficult to imagine challenge entries with German, French or other flags.
There is one exception to this which is Norway. Norwegians display their flag almost constantly on any occasion. Here you see an entrance to a shop selling ethnic items from all over the world. Decorated with Norwegian flag, of course.
