'Walls of kindness' have started springing up over Iran, allowing people to donate clothing for the homeless.
The walls, which simply have a few hooks, hangers and a shoe rack, invite people to give to those less fortunate than themselves.
The instructions, painted next to the donation point, are simple: "If you don't need it, leave it. If you need it, take it."
The initiative is believed to have started in the north-eastern city of Mashhad but has spread following a cold winter and economic hardship in the country, according to the BBC.

The idea was first started by an individual who wishes to remain anonymous, which is a shame because we'd like to give them a huge round of applause.
"This is a great initiative. Hope it spreads across Iran," said one Facebook user, according to a translation by the BBC.
Let's hope the idea spreads further.

This isn't the first random act of kindness towards homeless people we've seen this winter.
Just last month a commuter in New York was heralded a good Samaritan after giving a homeless woman the shoes off her feet while waiting for a train.
Kay Brown, 26, was on the Subway in New York when she noticed a homeless woman walking bare foot, without shoes or socks.
"I asked her what shoe size she wore and we were the same. I gave her the shoes off my feet and they fit perfectly," Brown wrote on Facebook.
"She couldn't have been more gracious. So I stood on the subway for 15 minutes in my mixed matched socks, then right before I got off the subway a gentleman offered me an extra pair of socks to go over top of my small thin ones.
"You see, I can buy another pair of shoes tomorrow. And he probably has plenty of socks at home. It's the middle of November and she has no where to go, so the least I could do is give her a pair of shoes."
