How does a Barbie knee joint work?

For all who always wanted to know how a knee joint works but never damaged a Barbie doll to find it out, here is the result. (I already got the doll with the broken knee joint.) I haven’t  destroyed the doll myself.   I think the pics explain how the position is held and why we can bent the knee joint three times.

Finally complete

In the last weeks I had the chance to complete my  1977  Superstar Barbie doll. She came with her dress, earrings and her ring.  Back then when she was released with a dress, a boa, a pair of  pink Superstar shoes, earrings, a necklace and a ring.

Here are some pictures of the now completed outfit:
