I found this in Cat Street last week, among a pile of old photos.
It's one of those tiny thumbnail photos, appx 4 x 2.5cm, and I nearly threw it down as a photo from someone's trip to Europe. But a little bell went off that it looked like the photos of Eu Tong Sen's 'castle', Sirmio, we've seen - and indeed that's what it is.
Based on the other photos in the pile, I'm guessing a date of the 1960s, but it could be anywhere between the 1950s and 1970s.
I'm not sure what the scene is either. Maybe a couple of the staff who worked at Sirmio, walking up the drive to work?
