A mystery mural that appeared after Extinction Rebellion protests in London has been put in protective casing.
The artwork appeared on a wall in Marble Arch when two weeks of climate change protests in April came to an end.
The graffiti is suspected to be a Banksy painting although the elusive artist has never confirmed it is his.
Westminster City Council said art experts advised them that the work was genuine and said they wanted to protect it because it generates so much excitement.
The Mural depicts a young girl holding an Extinction Rebellion logo, next to the words: From this moment despair ends and tactics begin.
The council installed a permanent polycarbonate case on Thursday after consulting art conservationists.
Iain Bott, the authoritys cabinet member for sports, culture and community, said: Our priority has always been making sure this street art remains in public view for our visitors to enjoy.
We want Westminster to be an exciting, vibrant place to be and are fortunate to have so many famous statues, landmarks and artworks on our streets – this piece is a welcome addition.
Earlier this month a Banksy painting was stolen from the back of a wall in Paris.
Mr Bott added: Banskys work generates so much excitement and attention, sadly some of that attention isnt positive – so we needed to take steps to protect and preserve it for the future.
