Graffiti artist Banksy has confirmed via Instagram that a recent piece in Port Talbot was indeed his.
A video posted to his official Instagram account on Wednesday afternoon had close-ups of the piece.
With the children’s song “Little Snowflake” as a soundtrack, the video shows images painted on two garage walls that form a right angle.
On one side, a child appears to be playing in the falling snow, sticking his tongue out for snowflakes.
The other side reveals that the “snow” is actually falling ash and smoke from a fire in a dumpster.
The video then pans up to show the nearby Tata Steel plant, which looms over the Welsh town.
Port Talbot was listed (wrongly, it transpires) by the UN this year as the UK's most polluted town.
