U.S. federal trademark · Serial No. 97774591
I sell enamel pins, which - if not known - are "flat brooches" but with original art (printed/carved) ingrained to make images and designs. They are fairly common in collector circles. (These pins are not made of "precious metals" but rather zinc. I do not sell watches though.)
