I believe this is the one that was doctored. Funny...the headline 'An American Tragedy' is actually much more appropriate for the magazine itself than it is for O.J. Simpson.
The worst TIME cover that I remember was the one of Newt Gingrich after the elections of 1994. They used a red filter and enhanced his face like 70" HDTV - huge pores and beard stubble. He had not been yet elected Speaker of the House but was going to be when the next session of Congress started. They just started their demonization in preparation.
