Rare paintings on fabric (I believe is silk). - $95 (Savannah)

They were purchased unframed by my sister during her international travels.
The large one measures19 inches by just over 22 inches.
The smaller ones are square and 11.
5 inches.
Background is dark blue it has metallic looking paint as well.
They have great NEW plain black frames.
They are very unusual and I have never seen another grouping like these.
