I'm always a sucker for before and after photos. I amaze over the beauty shots (they looked so plain before!), and intently study the home reno's looking for the little details. But these have got to be the most amazing before and after shots ever. Paris! The before's taken in the 1850's contrasted with modern photos of the same location. Beautiful! And, interestingly, not too different! Enjoy!
