A yellow man in swimming trunks and a rubber duck’s head. This could only be the work of one man, and just in case you were in any doubt, he has rather helpfully signed the piece over the top. It is of course Face the Strange.
I’m not entirely sure when he pasted thie piece up, it looks quite old, but I don’t recall seeing it at Upfest 2017, so maybe he visited Bristol after that and put it up, or maybe I just hadn’t registered it before. It is a fine wheatpaste and appeals to my surreal tastes.
