A reference via Museum Dokkum
The news report mentions a loan in connection with an exhibition at Museum Dokkum. That does not confirm that the Prentenkabinet is open as an independent venue.
Visits by appointment listed
Museumgids Nederland still lists visits by appointment. Whether that option still applies has not been established.
