Then I checked and the first Barbies appeared in 1959, so I guess my thoughts were correct :D

The car and her outfit would match my hectagonal-shaped lenses, 3" diameter pink sunglasses (bought, AND worn, in the mid '60s)

Think I had a dress like that too! woo hoo (Edit: I just looked at the pics again and YES I DID have that dress - however, mine was white with black bow and trimmings. I tell you, there are NEVER any new fashions lol)

What colour was Lady Penelope's Rolls-Royce in Thunderbirds? That was pink too, wasn't it? FAB1
That was 1965.
