The real National Park font is now available for Office
There’s a proper digital font version of the typeface used on US National Park signs. It’ll work with Office for Windows or Mac.
The original signs were hand-carved with a router bit.
At https://nationalparktypeface.com/ there are four options available: Light, Regular, Heavy and Outline.
They are available as a free download under a SIL License. OpenType fonts compatible with both Windows and Mac.
Back in 2016 we told you about another US National Parks font clone NPS 1935 which emulates the Art Deco typeface used on National Parks posters.
