In order to try and see the photos more clearly I loaded them onto our computer. I came to the conclusion that they must have been taken some time in the 1930s as there were no photos showing the results of the bombing which took place during World War II.
Considering they're tourist photos of landmarks, which rarely change a great deal, they're quite interesting, so I've reproduced them here.
*although teenagers as such didn't really exist until at least the 1950s, One day they were children and the next they were 'grown up'.
