You really know you are at a street art festival, when the bins that are provided for used spray cans are themselves sprayed. In this case by the talented and humorous The Agent. These minions were sprayed on bins around the Upfest site and added to the overall spectacle.
I met The Agent a day or two after Upfest, when Inkie was finishing off his piece on Dean Lane. He corrected me about the post I wrote about a Bearpit piece on the 12 July, a short time before the festival. He most definitely is from Bristol, and indeed I have a recent piece by him lined up for posting soon. All good fun.
