I was thinking the same about mine also, does look almost mexico in orgin, and for sure Folk art like, and yes it is twisted wire with Enamel paint in between, and the back is Spun Brass, lot different then any I have seen before, but seems to fit the Catagory. My friend did not give me a area of Origin, but for pretty sure it is early 19th Century in age, I will have to do some more consulting next time I see him.
