Steve, Thanks you! I think I have another hat from a Flensburg shop. I have never been to Flensburg so need to visit there one day.Super find, Steve.
Flensburg is right on the border between Denmark and Germany. It used to be a part of Denmark and therefore a Danish town, but after the 1864 war between the two countries, it became a part of Germany.
In 1922, it almost became a part of Denmark again, but the citizens of the area Flensburg lies in voted for it to remain in Germany.
Wish I had more on the establishment your Bowler was sold in.
