Sterling silver Jewel Art screw back little rose earrings

I almost forgot about these neat little rose flower earrings by Jewel Art that i bought on the same excursion as the Gecko find. These too are sterling silver. They are screw back. aia really like the applied patina or antiquing that makes the roses really stand out and give them more depth. By the way dose anyone know anything about the maker of these? First time that I've seen jewelry by this maker. These don't look near as old as the Geckos either. Maybe 40's or 50's? Anyway I hope you all enjoy these. Thank you.
