We arrived at the museum just before 11am on a Sunday. There were obviously quite a lot of tourists around, but we enjoyed the museum. The main focus is on his early work, with good explanations as to where his influences came from.
We prebooked tickets online, and based on the 100m queue outside when we left, is a must. Take your tickets to an employee, and they will show you where to enter by missing out the queue. Pay a few euros for the audio guide too - it lets you travel at your own speed, giving good and clear explanations at numerous points.
A free guided tour (in English) is provided on Sundays at 11am, but check the website for details as to when this offer is valid. We chose the audio guide over the tour and were not disappointed. Lots of prints, postcards and other memorabilia in the shop at the end.More
