Hmm I suppose you're right - the original eaton centers were considered art deco that were built during the 30s era- as is the the original eatons center in toronto (eatons college street) still considered an art deco style - those were built by Ross and Macdonald. I may have temporarily gotten my art styles mixed up lol..
and the outside does have some architectural elements above the doors that are better than say, plain curtain wall. Beautiful may be relative - I consider the circular middle area and the roof area of the mall beautiful. All that natural light really does add something, and it may be a bit gauche to make this comparison, but it reminds me of the crystal palace architecture a bit.
The hamilton buildings architect was Cadillac Fairview.
On that note hamilton used to have its own crystal palace in victoria park
