"Pendant or medallion [from Mohenjo-daro] pictures the unicorn combined with many sacred symbols of the Indus religion. The body of the figure has a womb-shaped symbol in its belly, the same motif is elaborated to form the frame for the pendant, which is also a common design for shell inlay. Two leaf shapes of the sacred pipal tree are depicted at the animals shoulders and rump. A ritual offering stand is placed in front of the image. 

The deeply incised frame and the symbols on the unicorn would have been set with inlay." (J.M. Kenoyer, Indus Civilization, p. 1

Gudea sculpture holding an overflowing pot which is an Indus Script hieroglyph. 

Gudea (Sumerian 𒅗𒌣𒀀 Gu₃-de₂-a) was a ruler (ensi) of the state of Lagash in 

Southern Mesopotamia who ruled c. 2144–2124 BC.He probably did not come from the city, but had married Ninalla, daughter of the ruler Ur-Baba (2164–2144 BC) of Lagash, thus gaining entrance to the royal house of Lagash. 

He was succeeded by his son Ur-Ningirsu.

Gudea’s link with Meluhha is clear from the elaborate texts on the two cylinders describing the construction of the Ninĝirsu temple in Lagash. An excerpt: 1143-1154. Along with copper, tin, slabs of lapis lazuli, refined silver and pure Meluḫa cornelian, he set up (?) huge copper cauldrons, huge …… of copper, shining copper goblets and shining copper jars worthy of An, for laying (?) a holy table in the open air …… at the place of regular offerings (?)
