This is a really interesting small piece by Bristol/Bath artist Harry Grech who I understand from his Bio has a passion for using spray paint. I don’t think he does much street work, or if he does I haven’t seen any which is more the pity because this is magnificent.
A wonderful blend of a classical subject and modern a modern style combine to create something quite special and fairly unique. I didn’t see the artist at work so am not sure what technique was used, but it looks like a stencil which might have been oversprayed with the angular sections… so difficult to tell. It would be great to see more of his work.
