Cast Iron Storefront

I love to watch Salvage Dawgs on the DIY network. Recently I saw an episode where they removed a cast iron storefront from an abandoned building. Well, guess where you can find a prime example of a cast iron storefront?  101 Story Abenue, right here in Florence, Texas!!  Look real close at the photo below.  Notice the black columns?  Those are cast iron and form part of the storefront. The remaining pieces are out of camera view.
