I recently acquired one and it has the back markings of the 1965 bend legs (1958 Mattel Inc. US Patented/US Pat. Pend) but has the blonde bubble hair (t's a tight bubble with no apparent hair part) with white lips. It's in a blue outfit, but underneath is half the red swimming suit - the bottom half. I got it from the original owner who got it she said mid-60s.
Thanks for your help.
