My sisters and I played with this doll and outfit when little girls.  The doll's legs are missing, but the rest in good condition.  I think it is part of the Live Action series, but I am not an expert.  Barbie's two-piece outfit is missing all the accessories, but it is in good condition.  Ken's shirt and vest is the only part that I have of his outfit.    Could not get a good photo of Barbie's rear, but it reads:    @1968 MATTEL INC, US & FOREIGN PATENTED, PATENTED IN CANADA 1967, OTHER PATENTS PENDING, TAIWAN
