[by Earl Blacklock] We’ve all seen them – the athlete or celebrity who, by virtue of their endorsement, can boost sales and raise profile for products and ideas. Companies line up for the opportunity to pay millions for the endorsement of a celebrity.  Remember the “I’m going to Disneyland!” campaign? Constance Talmadge was one of the champions of the endorsement game. If you’ve never heard of Constance, it’s not surprising. She was a star of the silent film era, a beautiful woman who made some 84 films before her career ended when talkies took over. Together with Mary Pickford, Douglas Fairbanks, and her equally talented sister Norma, she inaugurated the Hollywood tradition of putting her prints in cement outside Grauman’s Chinese Theatre.
