A coupon in our city pass brought us to the Stedelijk Museum of Modern Art. We expected to find Picasso (I think there was one
Picasso there) and his contemporaries. What we did
find was a very graphic photography exhibition, and many paintings and other works from lesser-known artists (at least, lesser-known by us).
Graphic photography aside, the paintings were very good, and it was an interesting visit, considering we'd already been to the Rijksmuseum to see the old masters.
