Balinese masks

hi, I've been given these masks and would appreciate any information regarding where they are from, and or what they are for , thank you

I think they are mid-20thC dancing masks from Sri Lanka. They have a long tradition of using masks in their threatres. Although India / Bali / other Indonesian countries are also possible.

Balinese (Indonesian) circa 1970's-80's, they were originally used as masks in ritual drama of epic battles between gods etc (Bali being a Hindu island in a majority Islamic country) however by the time these would have been made, they were being made for the tourist market. This doesn't diminish their value, interest or decorative appeal IMHO

Thanks for your input Apex. Much appreciated.
