In 1974 the Ideal Toy company released its Tiffany Taylor in an attempt to dislodge Mattel's Barbie as the top fashion doll. Tiffany, taller than Barbie at 19 inches, boasted a novel feature that Ideal felt sure would make her popular. The crown of Tiffany's head rotated to change her hair color from brunette to blond and back again. The mechanism that changed Tiffany's hair color came from the shop of Marvin Glass, a profilic toy inventer responsible for a number of toys including the game of Mouse Trap, Mr. Machine, and Lite Brite. As befits a fashion doll, Tiffany had a number of outfits that Ideal sold separately. By 1976, the last year she was sold, Ideal offered 16 different outfits with the doll, which it adverstised widely on television with the tag line ""She's what you want her to be." In the same year, Ideal offered Tuesday Taylor, a smaller version of Tiffany, with two hair colors. Tuesday was 11.5 inches tall--just the size of Barbie. Tuesday, of course, could steal all of Barbie's clothes.
