According to Keith Richards . . . .

I've been reading my "Rolling Stone Interviews '67-'80" and just finished reading one with Keith Richards in 1971. He talks about Rolling Stones Records with the "Kali" tongue. We all know what that image looks like and it truly has become a brand image for the Stones but in this interview Keith knows that it will become this icon. Kali is the Hindu female goddess with 5 arms, a row of head , a saber in one hand, flames coming out the other and she stands there with her tongue out. So now you know where that image came from . . . . .
