Swedish Campground (2004)
E.g. in Norway the sign is specifically described in regulations as referring to a "severdighet", literally something like "a seeworthy thing" but generally translated to "attraction". It's specifically regulated to mean that[1], rather than fornminne/ancient monument.
In Norway, you can for example find it used for the Holmenkollen ski jump, which is hardly an ancient monument[2].

An athletic facility that's been going since the late 1800s and has a dedicated museum and is of distinct local cultural importance kind of fits the "historical interest" part pretty neatly.
As your lovdata-link shows, there are six different signs for severdigheter, not just one, and in the local parlance severdighet typically refers to things like historiske steder, monument and so on. Unless something has a bit of history it's unlikely to get one of those signs put up.
The other 5 are for narrower, more specific use, and demonstrate quite clearly that the word "severdighet" in Norwegian has nothing specifically to do with historical interest. When you then try to insist that the general, catch-all sign does it feels intentionally obtuse.
To make this clear, here's an example of a sign to INSPIRIA Science Center[1], built in 2011.

Eventually we got HyperCard:
If I had to guess, I'd guess Henry Dreyfuss's Symbol Sourcebook. It was published in 1972, and it seems plausibly the sort of book someone like Susan Kate might have had to hand in the early '80s. https://www.societyofsigns.com/projects/symbol-sourcebook
Unicode does not quite cover it because it lacks context and meaning of combined codepoints.
Campgrounds have a normal descriptive “tent” symbol road sign in Sweden https://korkortonline.se/en/theory/road-signs/direction-sign...
More like, a place "worth seeing".
Officially defined in https://www.riigiteataja.ee/akt/126112024009?leiaKehtiv -> https://www.riigiteataja.ee/aktilisa/1261/1202/4009/MKM_2901... -> sign no 718.
Google translate of the official sign definition: "sign 718 "Sight" refers to the location of tourist objects (sights of interest to tourists, heritage conservation, nature conservation or other objects);"
This was long before the Internet when things like International Signal Directories were worth their weight in gold.

The "control" button is slightly weirder. Why is that a ^ on some of Apples keyboards, while only having the text "ctrl" on others. The "control" vs. ctrl isn't related to space, the laptop keyboard have "control", but my full size wired Apple keyboard just have "ctrl" despite the button being physically bigger.
