From the Contact form:

I am a librarian in the „zentrale Hochschulbibliothek“ in Flensburg, Germany and I am responsible for the textbooks, because we have a lot of students here which are studying teaching.
So I want to beautify my textbook-department with some instructive and interesting posters.  If you can donate any posters with the main theme [being] printing/letterpress please let me know. If you have something like this in poster size for our library it would be so nice. Thank you for your time and best wishes from the most northern part of Germany.
