Vintage hand carved heavy wood Palauan storyboard signed MUD

Description

This is one of my recent estate sale treasures.
It was brought home from Guam in the early 70's
Signed on the back by Mud
it has some awesome hand carved details
After much research, I am still unsure which story it describes
27 inches wide and 14 inches tall
it is an inch and a half thick piece of solid dense hardwood
I think she said it was snakewood, but I don't know
There is a steel loop on the back for hanging,
but you better have a strong nail because it weighs 15 pounds
Be sure to see my pics,
I will share any info if anyone recognizes the myth
and wants to share it with me
I'll put a low starting price on it and no reserve
