I was looking for a font similar to that of what the artisy Banksy has used on his 'if graffiti changed anything, it would be illegal'. I didn't post this in the font identification section as I know this is hand painted and not an actual font. I'm looking for something close which looks quite grunge like someone has taken a paintbrush and bucket and just painted words onto a wall rather than use a spray can. I can add paint drips etc but it's more just a similar font I'm after.

Thanks for any help
