I've managed to date and identify all the photos from Europe 1993 based on the itinerary and Dad's notes.

I've also scanned some of Dad's photos and added them including four views from the Eiffel Tower (it was a bit foggy), four photos from Sagrada Familia Barcelona, a photo under the Louvre's glass pyramid, another photo of the Queen and a photo of Stone Henge.

Meanwhile, here are some more recent photos of Sagrada Familia.
