In which museum is M.C Escher's masterpiece Metamorphosis displayed (especially version III)?

Question

I really hope you guys can come up with an answer, as I've been wandering around the web with no real success. I really hope I could find a poster of Metamorphosis III for my room. And yes, I am aware of the fact that even on a tiny scale it is hugely wide. But it's worth it, I'm sure you Escher enthusiasts will agree. Thanks 4 your help!
