The animals heads are typically seen in profile with slender almond-shaped eyes and upwardly curled appendages on the noses and the necks.
On this stone the runic text lies within a serpent that circles a triquetra, which would have been considered a high status motif.
[3] Because the runic text of runestones U 937 and U 991 have the same message, it has been suggested that they were once at the same site and formed a coupled memorial to the deceased brother Veðr.
This stone is classified as being carved in runestone style Fp, which is characterized by runic bands that end with animal heads when seen from above.
[6]Runestone U 991, which is composed of granite and is 1.5 meters in height, consists of runic text within a serpent that circles a central beast.
