Less than 20 years ago people were picketing against big business, calling it part of the "establishment" and blaming it for many of the world's problems. Today everyone's watching the latest takeover attempt, reading annual reports and examining P/E ratios. We feel it's our duty to give our readers what they need in this world, and in this world where corpor- ate raiders are kings and the stock- holders are pawns you'd better know the players because there isn't time to look for a scorecard. Fortunately, they all use logos. Some of these graphic symbols are as familiar as the face we stare at in the mirror each morning. Unless you've never eaten a bowl of Cheerios and read the box, you instantly recognize the big G of General Mills; and unless you've never sent or received a greeting card, the Hallmark crown is emblazoned forever in your memory. Often a logo is simply an artistic rendering of the company's name or initials or even their corporate mission. In many cases, however, the logo is abstracted - often to the point that it is difficult to recog- nize how it might have evolved to its present state. The brainteaser this time chal- lenges you to identify the logos (some with names deleted) of twelve U.S. corporations. We'll give a $25 prize to the sender of the first correct entry. And if I were you, I wouldn't ask my broker, he'll probably want a commission.
