We are looking for striking graffiti and urban art around South Yorkshire. This piece by Phlegm came third in a 2007 competition. If you spot some graffiti art email firstname.lastname@example.org with a picture.
Local urban artist and musician Kid Acne did this graffiti on a building on Sidney Street, around the corner from the BBC Sheffield offices.
Jim Lambert sent in this interesting photo of graffiti in a derelict warehouse in Sheffield.
Park Hill's development company Urban Splash commissioned Kid Acne to brighten up some of the old walls on the building site. The walls are temporary; they will be knocked down by the end of the development.
Kid Acne graduated from Sheffield Hallam with a degree in Fine Art in 2000 and in 2008 he was asked to paint the university's Psalter Lane campus. It took him two days to paint the four brick panels which stayed there until the campus was demolished.
If you spot striking graffiti art, take a photo and email it to email@example.com. We may include it in this gallery.
This picture by graffiti artist Kelzo depicts Sheffield Town Hall and the Supertram. It came second in a competition held by The Forum in 2007.
The Rolf Harris graffiti between Paternoster Row and BBC Radio Sheffield has been added to the wall over the years. Kid Acne's work can be seen on the left hand side.
Phlegm did the graffiti art on the side of The Rutland pub on Brown Street in Sheffield. Email your photos of graffiti art to firstname.lastname@example.org
You might recognise this unicorn from the previous picture of The Rutland. This one was spotted on shop shutters by the Wicker arches in Sheffield.
The characteristic gold paint and bold figures in Phlegm's work makes it stand out. He's from North Wales but has lived in Sheffield since the mid-1990s and works as an illustrator.
Sandra Barley from Moor Sheffield sent in this photo of a painting by Phlegm: "He has brightened up empty buildings on Rockingham Gate near The Moor out of the goodness of his heart," writes Sandra. "It has caused lots of interest from young and old."
Andolf was one of many taggers around Sheffield. Some think it's art but Sheffield Council's Street Force team, who remove illegal graffiti from around the city, find it an expensive nuisance. For more on Andolf, click on the link on the right of the page.
Another design by Phlegm, this time on a hydroponics [gardening without soil] shop on Castlegate in Sheffield.
Graffiti artist Rocket starting work on a temporary graffiti wall near Devonshire Green in Sheffield, 2007. Rocket started graffiti-ing aged 14 and holds workshops in Rotherham.
These ghostly graffiti shapes have been spotted near water around Sheffield. Mark emailed to say that he doesn't knew who painted them, but the 'ghost' is actually Horace from a series of ZX Spectrum computer games in the 1980s!
After seeing the water sprites on this gallery, Hannah Ashworth sent in this photo: "Thought I'd seen those ghosts before! I took this picture last summer, along the road to The Everyone Centre."
Chris sent in this photo: "It looks to be another picture by Phlegm? It's located on Cemetery Road, behind the supermarket."
