"The Masks"

So I've found this sculpture in one of Tehran's metro stations. It was very unique and eye-catching.
It surprised me to see it exactly in the metro, a place controlled by government. I could literally see the protest in it.

I haven't stayed in Tehran a lot, but as I visited Isfahan and Shiraz I didn't see anything like this all the art in those places was traditional. In the other stations there were also some sculptures and photos, but no of them gave me the feeling that this one did.

You really can read a lots of things from these faces lik:e anger, riot, scare, blindness, surprise, fight...
The metro in Tehran is very crowded and busy everyday, I relate this faces with the people inside it.

As I later read about it, the station where the sculpture was installed is located under theater.
The author put the name "The Masks" connecting it with theater and the roles the actors play.
He says the sculpture has 60 characters.
And he spend 4000$ to make and install it.

Later the management of the metro told him to remove it.
They consider it an something from the devil and as Iran has very conservative government they find it aggressive.
Maybe they also saw the protest in it.
The other reason, as they say, was that the management of the metro changed and they don't approve things done by the previous management.

And the author told them that he doesn't have enough money and equipment to do it.
What will happen to this sculpture I don't know.

I'm very disappointed, once in a while I found a very unique piece of art in Iran and they are going to remove it without an exact reason for it.

So tell me, what do you think about it?
