Stop Handgun Violence has implemented several media and public awareness campaigns, the centerpiece of which is America's largest billboard, located on the Massachusetts Turnpike adjacent to Fenway Park in Boston. In 2008, the 252-foot billboard, which Rosenthal owns, displayed the message "We Sell Guns! Criminals and Terrorists Welcome, No ID or Background Check Required," an ironic reference to the ease of buying firearms at gun shows. Previous displays, many designed by the
Modernista! ad agency in Boston, have held messages such as "You Shoot. Your Family Pays" and a fake ransom demand, "We Have Your President and Congress – NRA." The billboard is required to be removed by the current owner of the property no later than March 2015. Other billboards have displayed photos of children who have been killed by gunfire. ==Criticism==
