15/16" dia. quite thin brass case covered in engraved designs on both sides and holding a slightly raised beveled edge glass cover over a steel engraving close-up paper portrait of Harrison. A few very light tone spots on the background mostly at the right and with none on his image. The case is NM and displays Mint. Above, like a pocket watch stem, is a movable ring which also has engraved accents. The only example we've seen and with incredible detail on the portrait especially compared to the couple of known examples of sulfide portrait brooches.
