The initials JN (with a bit of the N missing)?
So a great big vanity pin?
Looking at his bio, expecting to see “rancher” as occupation… Which I did.
My WAG is it is a lapel pin for his cattle brand.
Not quite a square root,then.
Back in the '70s, the lambda was a symbol of gay liberation.
So, possibly a cattle brand, possibly inspired by his initials? That seems quite possible. Thanks for the suggestions.
I was aware of that meaning of lambda, so that did cross my mind. I don’t think Jim Nielsen supports LGBT rights, though. Thanks for the input!
That is not the “lambda” sign.
