 Five men who appeared in Marlboro-related advertisements — Wayne McLaren, David McLean, Dick Hammer, Eric Lawson and Jerome Edward Jackson, aka Tobin Jackson — died of smoking-related diseases, thus earning Marlboro cigarettes, specifically Marlboro Reds, the nickname "Cowboy killers".Wayne McLaren testified in favor of anti-smoking legislation at the age of 51.During the time of McLaren's anti-smoking activism, Philip Morris denied that McLaren ever appeared in a Marlboro ad, a position it later amended to maintain that while he did appear in ads, he was not the Marlboro Man; Winfield held that title.
