This carved black beauty measures 2 1/2" in diameter and has classic gold colored hand painted lines in the crevice of the carved curves. This bangle is really shiny, highly polished bakelite. I have another gold painted crevice bakelite piece that is a brooch of panther Art Deco silhouette.
Do a search on my shop search box. The geometric shape of curved lines took over the straighter lines, in the later Art Deco period.
