I think so. But how disappointing to see all the writing and mess surrounding this piece of art-grafitti. I spotted it whilst walking around Edinburgh yesterday, before the match, and wondered if it might be Banksy. On arriving back home, I googled it, and it seems other people have had the same thought. You can never be sure though. Not too happy with the rugby result, (Ireland won, Scotland were hard done by), but had a lovely weekend with friends, nonetheless.
The Banksy I found wasn't signed - I photographed it because it amused me then checked it was on his website - he authenticates them there. And that one is only partly there as another graffiti artist painted over it.
