James May and Autocar

James May is one of three hosts of BBC's hit TV show Top Gear.  He is an established automotive journalist, having written for The Engineer and Autocar magazines. In 1992, however, May was fired from his position at Autocar.  In one issue of the magazine, each spread featured four reviews and each review started with a large red letter.  Take a look at a picture of the magazine.  Each large red letter is part of a phrase hidden within the magazine.
