Sasha dolls are a type and series of doll created by Swiss artist and dollmaker Sasha Morgenthaler (1893–1975), produced in Germany and the United Kingdom beginning in the late 1960s.
 Popular with collectors, Sasha dolls are characterized by their individualism, their realistic expressions, their unique color, and the extreme attention to detail in the manufacture of the dolls as well as their clothes.
 It is said by Juliette Peers that: "Sasha dolls are renowned for possessing a solid intellectuality."
 Morgenthaler created face sculpts for her dolls with subtle expressions, not artificially exaggerated smiles: her concern was that children surviving the horrors of WWII would not relate to such happy dolls in times of terror.
 It was said of Morgenthaler herself, as a child, that "When she was sad, she did not like her dolls uncompromising smiles.
 Once she grabbed a nail file and scraped off her doll's false grin..." In her own words, "No grotesque caricature can awaken a child's true feelings.
 A piece of wood, barely carved, is far superior to a conventional doll with an exaggerated smile."
Sindy is a British fashion doll created by Pedigree Dolls & Toys in 1963.
 A rival to Barbie, Sindy's wholesome look and range of fashions and accessories made it the best-selling toy in the United Kingdom in 1968 and 1970.
 After Marx Toys' unsuccessful attempt to introduce Sindy in the United States in the late 1970s, Hasbro bought the rights to Sindy and remodelled the doll to look more American.
 As a result, the doll's popularity declined and Barbie manufacturer Mattel filed a lawsuit for copyright infringement, which was settled when Hasbro agreed to remodel Sindy's face.
 During the 1990s, Barbie's share of the doll market continued to grow while Sindy's diminished, which led to Sindy being delisted from major retailers in 1997.
 Hasbro returned the doll's licence to Pedigree, and the doll was relaunched in 1999, manufactured by Vivid Imaginations.
 Sindy's 40th anniversary in 2003 saw a new manufacturer, New Moons, and another relaunch and redesign.
