This figure is from the rich archaeological site of Chandraketugarh in West Bengal where many terracottas have been excavated.
A female holding a hide-covered drum resting on a cloth-draped stand is hollow with a plain back and a base. Like several other pieces from this site, it seems to have been designed as a rattle because the hollow body deliberately contains what sounds like clay pellets.
