I don't go to museums enough anymore. Or do enough to find out about the artists and groups of artists that most intrigue me. For example, P. S. Krøyer. I once had to suffer through an 'easy-reading' book about his erstwhile wife, Marie Krøyer. The book was the suffering part (it was part of studying for one of the many exams one has to go through in order to show that one is learning Danish, and was really quite tedious), but the silver lining was that these people led interesting lives (in the case of Marie, it included a torrid affair; in the case of P. S., well, he was basically insane.) And produced attention-getting art.
The painting above is, of course, Hip, hip, hurra! and is normally housed in Gothenburg. But for now, it's closer to me, in Arken. With many other paintings from the 'Skagen painters'. I'd say come to the Copenhagen area to see it, though maybe not on a Sunday afternoon, as the place was packed (only this part of the museum; the other exhibits were conspicuously empty).
