HAS Banksy left his mark on Brentford? Simon Tang is convinced this 'running tap', which he snapped last week, bears the renowned graffiti artist's unmistakable hallmark.
The photographer first spotted the small painting, which appears at the bottom of a disused building in Brook Lane North, about a fortnight ago.
He believes the tarpaulin-covered building, which lies just a stone's throw from the M4, may have caught the notoriously secretive artist's eye on his way from London to him home town of Bristol.
"It's really nicely done and looks pretty genuine to me," said the 35-year-old father-of-two, who lives in nearby Strand-on-the-Green. "He's from Bristol and he's always in and out of London so my theory is that he must have seen this building and thought 'that's an interesting building, I'm going to tag that'."
Bankys' stencilled portraits, which often have a political theme, have sold for tens of thousands of pounds.
A documentary about the artist, Exit Through the Gift Shop, was nominated for an Academy Award this year.
This is not the first time his work has supposedly appeared in Hounslow. About three years ago a mural of a grumpy looking young girl below the word 'smile' appeared on the side of the North Star pub near Hounslow train station.
Mr Tang spotted the Brentford 'Banksy' while he was in the area as part of a photography project on the town.
The project was fuelled by his fascination with the town's history and the gradual decline of its once-graceful buildings into disrepair. He is looking for a local venue to display his work. If you can help, visit www.simontang.co.uk and get in touch.
