Here's some interior shots at various pavilions. The slides are unlabeled, and my knowledge of the 1958 Exposition is minimal at best, so some of these are unidentified.

I love the tree (or lumber?) exhibit here. This could be in the Canadian Pavilion. Note the dominant color scheme at the fair: red, yellow and blue; much like the palette the Eames used in the 50s.

Canadian Pavilion interior. More yellows, blues and reds. The modernistic mural at the end of the second story deserves note. The large map of Canada on the left appears metallic.
