Maybe not as well-known, but certainly as symbolic as Time’s “Man of the Year” covers, Time Magazine’s X covers have marked the historic end of American enemies. Osama Bin Laden is about to join the ranks of the famously X’d out.
Then in August of that same year, the dropping of two atomic bombs on Japan triggered Time to illustrate the fall of the rising sun. It is assumed that the red in the rising sun symbol was the reason for using black in the X instead of the red that was used in the other covers. It is also the only cover that uses that style of X – more of a charcoal-drawn feel where the other X’s appear as red paint sloppily painted.
