Every year since 2001, networks and news organizations have commemorated the anniversary of the September 11 terrorist attacks with specials and documentaries, dramas and retrospectives. This year, the 10th anniversary of the Al Qaeda-perpetrated tragedy that claimed the lives of nearly 3,000 people at the World Trade Center, the Pentagon and Shanksville, Pa., is the focus of stepped-up media coverage, with more than 50 programs dedicated to the event. I have decided to design some commemorative posters to reflect on the events that took place on 9/11
