This is a pictograph of an archer with an angular bow and an arrow. His stance is suggestive of someone on horseback.

This is Mahadevan's sign number 1069, which I have redrawn to better reflect the original.
You should note that the archer is portrayed holding the bow string rather than the bow. The string is at rest , but the bow shape resembles that of the drawn bow.
The shape of the bow is relevant. It determined what could be killed, from what distance, and at what speed. It may also indicate where the archer came from, because angular bows are associated with western Asia.
It is also worth noting that the angular bow is realistically portrayed as being shorter than the self bow.
