I've been to the Van Gogh museum in Amsterdam, and I was a little disappointed because there were no pictures of some of his most famous work - "The Starry Night" and "Starry Night Over the Rhône".
Well, it is well known that Van Gogh artwork is in public domain, according to this question.
And I also know that these artworks are in the MoMA (New York City) and in the Musée D'Orsay (Paris). But why can't the museum use a replica? Or sell derived artwork in the museum shop? Or in the art books sold there? Or even tell us about these paintings during the history and life of Van Gogh presented in the museum?
It was like these paintings never existed!
