Mohenjo-daro: Seal: M-663 a: Sayid Ghulam Mustafa Shah and Asko Parpola, 1991: Corpus of Indus Seals and Inscriptions: Volume 2: Page 30: Collections in Pakistan: Suomalainen Tiedeakatemia.
There is only one extant example of this Indus sign.
Seal M-663 is damaged and the inscription is incomplete. Therefore, any translation has to be tentative. One possibility is 'tea growers'.
