Quite A Walkway

‘Herr Doktor’ wondered if I had any information on  the Leuchtturm Roter Sand, and I do indeed.

Luckily this book is full of superb illustrations covering every aspect of this particular lighthouse.

The only minor drawback is that the text is in German. OK for him, but not so good for me.

He thought that I make a very interesting presentation. 

Indeed it would make a great presentation talk. This particular lighthouse is made out of steel. Luckily the book is full of technical drawings but it also full of socially related documents.

I await his next question.
