I discovered the delightful website Ablak a múltra. The name means "Window to the Past" and it places modern pictures as the backdrop for older photos and matches them up. It's a visually striking way to see the changes in Hungary over the past century and how that change has affected the visual aesthetic of people, as well as the places themselves. Signs and details aren't the same and some buildings show serious decay. I highly recommend looking at all the locations for some truly interesting contrasts between now and then.
Take a look!
