Because Mr Pressibus exists ! He is an employee of first class (what a promotion !), in the city hall of Cinq-Mars (french name...). Tom Poes and Mr Bommel are living near. As he has often his nose in the archivs, his name was good for an association (created in 1990) which wanted to put in its name a tribute to the dutch Master. It allows to remember that in some french regions, as Lille (Panda), Nancy (Panda), Nantes (Mr Bommel), he was also a european Master, as swedish or german readers may testify elsewhere.
Do you know that Pressibus means "More quickly" in latin ? Good name for a city hall employee, of course...
His original dutch name is Heer (Mister) Dorknoper.
