Common Looks (sincerely)

Barbie has had an interesting beginning and a lot of plastic surgery through the years (understatement there but OK).  There have been a wide variety of moulds used to produce her face (and mould produced on her face, it might not be as pure as a Petri dish but it's more fun.) 
So is yours a true Vintage, Mod, Pink Box, Collector's Edition or Reproduction (who cares but have a read anyway.)

1966 was the year the most common Barbie body was copywrited/patented, it is not an indication of when the doll was made. (that can be told by the toxicity and smell of what she is made from)
The best way to tell the approximate year of actual manufacture is to look at where she was made (Mattel promotes her as an All American Girl, ahem....she is and always has been Asian, except for a brief time in Mexico.... see below)
