Nice real photo used as a postcard. It was sent to USA but the stamp was unfortunately removed which devalues it significantly. This sort of pictures were probably on sale in some the photo studios mainly to tourists in the 60s and 70s.
These two photos were from a private collection possibly taken by an expatriate. There are no details on the back to mention location or date. I think they are possibly taken soon after the war but could be a lot earlier and in the vicinity of Kota Belud.
This came with the other two photos above and the only information given was a beach near Jesselton. I do not think it was Tanjong Aru. It was possibly Likas or a bit further north.
This is my contribution which was taken a few years ago while waiting for my flight at the KK International Airport.
