Artists’ guide online
The Künstlerhandbuch online or artists’ guide online is a database with information on artists resident in Düsseldorf with their information, contact addresses, résumés and works.
If you are going to be in Düsseldorf for a while, Art:cards will give you free entry into all of Düsseldorf’s museums for a year. There is also a happy hour for guests not staying quite that long – many of Düsseldorf’s museums will let anyone in for free an hour before they close.
