Titled “Seasons Greetings”, the graffiti mural depicts a child playing in what appears to be snow. However, the second half of the mural, around the corner of the wall, shows that the snow is in fact falling ash from a fire.
The piece, in the Taibach area, appears to be a comment on the town’s industrial heritage.

The secretive street artist – believed to be based in Bristol – confirmed on social media he was behind the piece after it was spotted.
Art dealer John Brandler, who paid a six-figure sum for “Season’s Greetings”, said the work will be displayed in a new gallery in the Ty’r Orsaf building after being moved on 29 May.
The wall featuring the art weighs about 4.5 tonnes and needs to be covered in resin first. It is currently protected by plastic sheeting and 24-hour security, after appearing on the site of Ian Lewis’s garage just before Christmas.
“They're putting the resin on the back,” Mr Brandler said. “Then fixing bits of chipboard to the back of that. Then they're putting a special crate around it, a bit like a sandwich.”
Mr Brandler invited members of the public to come and witness the move, calling it an ''historic event.''
