As for this example, there's at least one and probably 2 artisan trademark identifiers present. The upper one is called a "comma" and the one below may be one or another type, but I'd have to see it more clearly to tell which for sure. There are at least 5 types of these and maybe as many as 7. Five so far have been given names. [img]https://photos.imageevent.com/drumaholic/elvinscymbals/websize/pre-trans.jpg[/img]
