After digging around for a while, we still don't know what where this adaptation was taken from. The woman on the left is holding the "mallet of fortune", suggesting that she represents Daikokuten (大黒天), the god of great darkness or blackness and one of the Seven Lucky Gods. The woman on the right carries a fan with an image of a carp on it, a classic image of Ebisu (恵比須), the Japanese god of fishermen and luck and another of the Seven Lucky Gods.
