I'm not likely to make a habit of posting painted signs (though there are some great ones about, like the MJB Coffee sign in Old Oakland that was posted on Oakland Daily Photo and Fritinancy), but this one caught my eye because of the "unnecessary" quotation marks.
There's a whole blog devoted to abuse of quotation marks, fittingly called The "Blog" of "Unnecessary" Quotation Marks. They produced a book to which I contributed a photo (taken across Lakeshore Ave. not far from this one, oddly enough.)
