It is amazing the amount of little-known mid-century modern architecture that abounds in this city. This photographer did a fantastic job tracking much of it down.

There's some really interesting hidden gems in OKC for architecture geeks. I love it.

Looks like a lot of Tulsa in the photo set to me..
