Vintage Copper bamboo frame painting on velvet young girls. Signed 10.5x13.5”

Vintage Painting on Velvet. Signed by artist. FMJ. Two young Native American girls painted on velvet. It’s beautiful! Frames are copper bamboo 2 Frames measure 10.5”x 13”5 Painting alone on velvet measures: 8x10” One of the back came opened and I noticed it had some writing on it (see last photo) unsure of what it means. It looks like it was 1/10 then there’s a 7 below. “Copper bamboo” and “Reg-gl”? Not sure of the meaning. Please note: price is extremely low for these two together in the frame, the age, the artist and the velvet. So price is fairly firm. Thank you !
