What can we do wth Buddhist dance mask (skeleton face). Some1 gifted me, is it good omen to keep in house?

It is a blue coloured mask of metal/ alloy with three red eyes and 5 skeletons near forehead and swaying/ burning hair. I dont know if its to be kept at home or not? If yes, which direction? Does it bring goodluck. I seriously need luck and cant afford to keep anything at home which is acting the other way round, please guide me Buddhist friends.
