A square steatite unicorn seal with a unique inscription was found in the street debris on the inside of the city wall. The two sets of signs on the right hand side of the seal would appear in reverse, i.e.
Large unicorn seal (H99-4064/8796-01) found on the floor of Room 591 in Trench 43, dating to late Period 3C. This is one of the largest seals found from any Indus site.
