Every girl born since about 1955, as well as her indulgent parents and her dismissive brothers, knows the story of Mattel's phenomenally popular Barbie doll and its amazing success. Most can recite the statistics: that all the Barbies purchased--strung head-to-toe--could reach the moon and back; that 95 percent of all American girls (ages three to ten) own an average of eight Barbie dolls; that two Barbies are sold every second somewhere in the world. In the 1960s, Mattel introduced Francie, Barbie's Mod cousin, who wore hip miniskirts and patterned tights, and maxi skirts with boots. Francie signaled the British Invasion in the Doll World. Francie's friend Casey followed, and the two of them made way for waifish Twiggy, the popular model from Canby Street and first celebrity doll to join the Barbie family.
