its not a Banksy,Sounds like it, but that certainly wasn't the answer he was expecting !
Everything that wasn’t worth £500 to £1k lolI nicked a piece of art from a derelict building once but am too scared to do anything with it. Its worth between £500 to £1k but just sits wrapped up in my loft. I felt bad to start with but not in the slightest now cos the place was sold a couple of years ago and I walked past and saw everything else in the house had been just dumped in a skip. Maybe I should disguise my accent and take it on Antiques roadshow
