I've had a look closer to home (Thanks Jim), Jim referred me to the link to Krieger's work found on this forum. See plate 7.

Can anyone here provide me with larger images of these plates by Krieger? The Kampalins in the images and data that comes the image in plate 7 indicates this piece presented by me is also from the Maranao people.
