I’ve been to enough small county museums around the West to know to look for their barbed wire collection. It’s usually a small board or shadow box with a variety of foot-long samples.

Some are clearly local efforts, but I’m wondering if there is a supplier of barbed wire collections for these museums?

I did a bit of googling and found this illuminating article about the Paso Robles Museum. The biggest collection is the Kansas Barbed Wire Museum, known as the barbed wire capital of the world. There are also collections available on Etsy if you fancy your own.
