Postscript: if you click on the Simpson Grierson link above, you’ll be taken to a web site where the logo doesn’t match the one in the ad. The symbol is the same, but the typeface and the positioning of the words Simpson Grierson are different. Someone flunked the paper on integrated marketing communications.  

Post-postscript: because of the one error, I am getting more and more bugged by this. The copy says Simpson Grierson has many lawyers. Then, surely, the headline should read Which Lawyers Are Number One? since it is answered Simpson Grierson. And, I assume, it was once Messrs Simpson and Grierson, so that’s two already.
   In the copy, it says one of their lawyers won some ‘Dealmaker of the Year’ award, so if the big headline is correct (save for the missing question mark), then it should be his name that appears in reply.
   I hope the law firm can present a persuasive argument to these points, because if anyone ever hired them, they would expect that, at the least. But if a simple one-page ad can’t be correct within itself, then what chance does one of its legal arguments have?
