Brick with 'Indigo' grafitti. You will want to use a different UV set for the grafitti map or edit the map size in Photoshop first. Bump and displacement maps included. Brick is quite low-res.
Very nice, and perfectly serviceable as a simple brick texture. I would, however, suggest that you upload a better preview. While the texture itself can look pretty darn good on a small number of samples (100 looks pretty darn good for the wall I'm using it on), it's still a bit grainy.
Nice bricks, but the graffiti would be better as a patch. :)
