At last (thank you Paul) I have located The Paintworks wall, one which has been used a couple of times for the Bristol Womxn Mural Collective. This magnificent beetle painted by Nina Raines which dates back to September 2021 was a piece from a BWMC paint jam.
Nina Raines is a fabulous artist, who doesn’t paint with a particular style or subject, but is incredibly adaptive. I would struggle to identify her work if it was unsigned. The beetle is so beautiful and Nina Raines has managed to capture the iridescence of the carapace perfectly. Look out for more pieces from this wall.
