An Irish street artist, Maser, and musician, Damian Dempsey, have joined forces to create a large-scale outdoor collaboration, "They Are Us", which celebrates Dublin city. The beauty of the project is that it appears all over the city, in nooks, crannies and alley ways.

The pair combined their powers, Maser's art and Dempsey's lyrics, to create a street art project which celebrates their 'dirty auld town'.

They say their project is "a tribute to the city: northside and southside, the visible and the secret, the good and the bad."

All proceeds from the project will be donated to the Simon Community, an Irish charity which works with homeless people.

Here are some images from the project:
