I have never driven across the US/Canada border. I have either flown or ridden on a car ferry. Apparently if I had drive across from Washington I would have seen this:
“Non-Sign II” is a permanent installation at the Land Port of Entry in Blaine, Washington.
The idea is to frame the space. Rather than an advertisement this is a non billboard, framing the sky.
I love how delicate the edges are.

There is video of the installation process here
