David - if its not too late for you to see this - by all means take the building tour. There's a lot of Art Deco on the 'inside' -- old corporate offices, etc. that are really terrific examples of the Art Deco era. As I recall, the tour takes you up to the mezzanine so you get to see some of the building 'up close'. Don't forget the museum(s) downstairs - the one that replicates parts of Cincinnati has a great train layout - along with streetcars. I think it's S-scale.
Thanks for the ideas. Unfortunately, I didn't check back in for a few days. Perhaps someone can clarify - I was talking to a fellow whose name I've blanked on - something Morris? - in public safety at the museum. Asked him about the model train layout, and he said it was no longer there, or off limits, or something. Of course, I should have gone down to check for myself, but didn't. Oh, and according to the website, tours are only on weekends - though maybe I should have tagged along with one of the school field trips. Lots of schoolkids there.
Beautiful building. What it must have been like in its heyday.
