A two line border surrounds the outer edge of this stone.
The plaque has an illustrated panel on either side. A flower at the top of the panel is supplemented by an abstractly engraved stem and leaves.
Remark
The tympanum's images include a oval skull with round eyes oriented horizontally. The mouth/teeth is simply engraved as a segmented line.
The traditional wings on either side of the skull appear more organic with an outer skin/edge and a segmented inner space.
