Although I am confident this is a Tom Miller piece, with his trademark explosion of swirling colours, it is not signed, and so there is that tiny little nagging doubt about it. However, since nobody else in Bristol paints like this, I will attribute it to him anyway.
I’m not sure if it is still there or not, it has been a week or two since I did any street art hunting in Bristol, but most of his recent stuff has been tagged and oversprayed unnecessarily quickly, which is pretty annoying really.
In this piece, a motif he uses a lot, a heart, is surrounded by a chaos of colour. A nice piece.
