The big doll connection (as I SEE IT)

 Tammy, Susi, Sindy, Fleur and Bibi- Bo are all fashion dolls from the 1960s– 80s, each with their own unique origins but with some clear design connections between them. 

Susi (Estrela, Brazil) was launched in 1966 through a license from Ideal/Tammy, while Sindy (Pedigree, UK) was introduced in 1963 based on Tammy and even used Tammy’s slogan. 

When the Dutch Otto Simon lost the license for Sindy in 1978, they created their own doll – Fleur – inspired by Sindy but with their own design. 

Bibi-bo (El Greco, Greece) was also launched in 1980. Here connection to Sindy or Tammy isn´t that clear but I have seen resemblence in body type.

Overall, several of the dolls share body measurements and facial shape (e.g. Susi/Tammy/Sindy) and have similar target groups and clothing styles (youthful 60s– 80s).
