Philadelphia Concert Hall
Demolition doesn't usually look like you just sawed off half of the building, but out in Philadelphia, that's how the Concert Hall was ultimately destroyed. You can still see some of the history inside of its now-opened walls. Up top are the balconies, now falling, and below are entrances to the main room. All that's missing is the stage (and the other half of the building...).
Un-Upholstered
When you're settling into your favorite chair after a long day of work, you don't think about all of the stuff you're really sitting on. Beneath this fine leather covering was a collection of wood, springs, cotton, lining, and more. As long as you have good upholstery though, you'll never have to consider this mess. Out of sight, out of mind!
