Mask-Origin,Age,Danced or Not ?

Here's a mask that appears Tibetan to my amateur eyes.It's 10 1/4" long by 7" wide.I'm looking for some ideas about where it's from (Tibet,Nepal ?),guesstimate on age,and was it danced or is it a wall-hanger ?
PS-I was inspired by Charlie's recent Mask post-thanks Mate.

 

I'd say wall hanger - no signs of wear on the back.

 

Thanks for the feedback Evely.Ethnic stuffs tuff for me to date.

 

not carved out on the rear, for wearing...

 

Right,right-too flat.

 

Interesting mask. I don't, however, see a lot of finesse in the carving. Just my opinion.
