The Museum of Popular Culture (MOPOP) has an exhibition of costumes and props from famous movies entitled, Fantasy: Worlds of Myth and Magic. While this is not a permanent exhibit, it has been up for a number of years now. This photo is from 2014 and it appears the exhibit was installed in 2013. Of course, the Cowardly Lion costume is iconic, but the craftsmanship and materials fo the guard's costume is stunning. Click on the photo to link to the exhibition on the MOPOP site. Unfortunately there are just a few photos and a brief description on the MOPOP site, but if your interested there are a number of in-depth reviews if you google the exhibit.
