Is the EC on the felt part of the blotter ?? Doesn`t look like the bronze part !! Can you tell if it is indeed cloisonné or is it champlevé ?? Champleve is done by filling in indentions then firing the enamel and filing/buffing smooth,,cloisonné is done by soldering individual wires around the area to be enameled which creates the border and then colored and fired !! No indents in cloisonné !! Both have a similar look but cloisonné is much more detailed in the process !!
