The mark is ESY. I’m at a dead end with identifying it.
It could be Sampson Yazzie with something before the SY. The style is very similar to his.
Thank you. I did feel like it was a Yazzie. But the E threw me.
The “E” looks like an upside down “3” to me. Is there another character in front of the “E” under the band? Wondering if it’s a numeric sequence.
