I found this collection of graffiti just off Vulture Street in West End recently.
The old man and the bird in a sack image reminded me a lot of a puzzle game I played a few years ago, Machinarium.
These sort of quirky images are what I find really interesting. They take a rather bland, and in this case boring grey wall and give it character and life.
As someone said using Scrabble tiles, “Grey is the real art crime”.
