Masterpiece painting?

I walked past this on the way home and thought it looks familiar. Then I figure out it bears some traces of Mark Rothko’s painting style (hope I won’t offend anyone here). You really should have a look of this painting to get what I mean; and click here if you want to see where I took this photo. It is actually a plumber’s advertisement which says: “unclog drain” and his phone number. Now you only need the area code.
