At 9th Street and Avenue C.
To be honest, this sign makes me sad. Someone wanted to start a business and they went to the trouble of making all these fliers (there are many taped up along Avenue C). And then they went and spelled the name of the company incorrectly. Unless they do mean Cinderlla's and not Cinderella's. (And I'd argue that Cinderella's isn't the best name for a cleaning business...) But I'm probably thinking way too much about all this.
