I've kept this postcard in my drawer for some times.
I have no idea what does the symbols representing for.
It is kinda like drawing of the fairly tales from the earliest ancient, known as Anthropomorphic Motif.
Those symbols inside the big circle are the intricate motifs which I believe is inspired by animal and plant. When the beads are woven repeatedly following the design and it can turn to be an exotic accessory like the photos below.
