I really don’t know very much about Piewaster. I know that he has painted a few pieces in Bristol over the years, but never enough for me to become familiar with his work or identity. This is a recent piece from the hoardings at Greenbank.
One of the elements that I think might be common to his work is the eyes that decorate the piece. I know of at least two other pieces (probably unpublished on Natural Adventures) by Piewaster and they had the same eyes. The letters spell out WASTER in two style/colour forms, one a hollow blue line WSE, and the other solid grey letters ATR. The whole thing is beautifully painted and is the work of a talented artist.
