These photos of Roman ruins were taken in 1966 by my grandparents. These images are scanned Kodak slides, and they have not been altered.
The first image with the inscription is near the Basilica Aemilia of the Forum. More information can be found on the inscription here (97A23.11).
I’m assuming the last image is also in the Forum, and the other slides are some interesting takes of the Colosseum.
