Just a drawing, after a picture in the newspaper of last Thursday (Volkskrant, 30-06-2016). In fact I have not read the article, but the picture by Derick Daily hit a string.
Today a fellow sketcher, Roger Klaassen, made a drawing after that picture, and I decided to do the same. Just for fun. Here is the link to Roger's blog: http://rogerklaassen.com/wordpress/blog.
