On some sherds, two signs of the Early Indus script (Kot Dijian Phase) appear together. The complete shapes of these signs can be seen on later seals carved with the Indus script (see 43). The sign on the left eventually becomes one of the most
Ancient Indus civilization writing.
This sign was carved onto the pottery vessel after it was fired and may indicate the type of goods being stored in the vessel or the owner of the vessel itself.
Many sherds inscribed after firing have single geometric signs. This collection of Early Harappan sherds from Periods 1 and 2 (c. 3300-2800 BCE) show a range of geometric signs that are roughly similar to later signs in the Indus script.
This fragment of a mold used for making large storage jars has three pre-firing graffiti signs. Such symbols when combined together may have served to indicate the name of the owner rather than just being abstract symbols.
These particular symbols made on the bottom of terra cotta vessels prior to firing were probably made by potters during the Kot Dijian Period in order to identify their own vessels or ones being made for specific customers.
