Künstler Script Black  Vorgeschlagen von wawahaha 

Your script seems to be hand painted onto a storefront...
It is very close to Commercial Script http://myfonts.us/td-LCw4HO
which is close to Palace Script http://myfonts.us/td-uhNbKP
which makes me thing someone may have used Artscript as a base. http://myfonts.us/td-CPKiaD

I hope someone here knows if an actual font was used. It would be interesting. Sorry I can't be more helpful.

Nice!!! Good Eye there...
