Another gratuitous women wrestlers post.

 Taking the hint, here's some more ladies trying to pull each others arms off. 

 Clara Mortenson squeezes her struggling opponent (1950s?)

 Britain - 1980s?-Busty Keegan has Leather Lena Blair in an awkward predicament

 Mexican luchadoras - somewhere in the 1980s

 More Mexican action - Estela Molina hoists up American visitor Vicki Williams

 Two German girls from the 1960s: Hanna Witkowski v Herta Beckers

 Princess Paula bends Tracey Kemp's arm in a manner it was not designed for.

 Unknown - Probably 1950s

Now I'm no expert but there's no way that isn't going to hurt.
