Hundreds of millions of people, including more than 330 million people saw these iconic letters in 2017.
They are all over our national parks.
The letters spell a variety of messages. They identify a park. That pond. A path. An overlook. Everything you see in a park.
Yet, ironically, that familiar, popular type of lettering could only be found outdoors.
That was until Jeremy Shellhorn came around.
Shellhorn worked as a designer-in-residence for Rocky Mountain National Park back in 2013.
The story goes he was creating the park's newsletter when he discovered there wasn't an actual version of the font that is used on all those national park signs, not only the park in Colorado, but national parks across America.
With a little research, he discovered the park signs were actually created by a device called a Computer Numerical Control router that carves the letters into the wood to make that distinctive clean look with the rounded edges.
