VTG I Spool of Blue Thread Sterling Charm

An old sterling silver sewing charm of a blue spool of thread by the R.L. Griffith Company that I suspect is now pretty rare. Most of the enamel has held up save for a few spots visible in photos shown from multiple angles, including top & bottom. Approx. measurements, photos 12-13. Griffith hallmark, last 2 photos, is on the ring & was extremely difficult to capture, but you will see the "G" w/the arrow through it, next to "SS" for sterling silver. Pretty good condition considering its age!
