Tricks of the mind, I saw it two years ago and now had forgotten it. On seeing it now it seemed familiar. I expect that is what happened here. Yes it is like Monart Cloissone but nothing to do with the Ysarts. It is a technique used widely and in variations.
Datewise, it could be 19th century or 2003.
Can you do a better (2 years of technology advance) pic of the mark Ray?
