Newport Channel Inn....

I found this postcard in Oslo last year and I´m curios to know more about this place... perhaps some of you people know the story..? Was it more to it than the A-frame? A backyard pool maybe with some tikis around it....
Not sure of when the photo was taken, but the car seems to bee a mid 60s mercedes? The signs look erly 70s? But the first thing they tell you on the back of the card is "color TV" so when was that not standard yet?

This is how it looks now....sad.
