Yoruba Glass Beaded Diviner's Panel 51" Wall Hanging

Description

I have what I believe to be a vintage Yoruba Glass Beaded Diviner's Panel, wall hanging Nigerian Art.
Measures 51" long from edge to edge, not including the hook.  5¼" wide.
It seems to be a linen on canvas material whip stitched to the backing.  White, yellow, red, blue, and black glass beads and cowrie shells adorn the front.
In vintage condition - there is staining on the back and some of the cowrie shells are deteriorating, but the beading is in excellent shape, with none visibly missing or loose.
