Just so we don’t hijack Tal’s thread any further than we have (ahem), I’m making a whole new thread for this!
These are the legs in question:
Props to the person who can actually tell me whose legs they are. I’d give you more than props, but unless you want a child or two, I’m all out of anything good to give as a prize 
Anyone? I’m dying to figure it out now!
Just don’t try Googling “legs” Images with SafeSearch turned off. 
My first guess would be Mitzi’s followed by Betty’s.
My first guess would be Betty’s. That’s Betty (“Legs”) Grable. I can’t find an image that matches Izz’s though. I’ve googled some images of Mitzi Gaynor, but I do not think that those are her legs. There is a picture of her wearing a garment similar to the little that is shown, but, again, the legs do not quite match the picture.
Still, it’s fun looking. If I don’t find a matching image on Betty Grable, I’ll examine Ginger Rogers’ legs after that…
I thought this might be a fun activity for at least a few of you…
No luck with Cyd Charise or Juliette Prowse. This is grueling work, you know … 
Yes, I know. I’m a slave driver, what can I say 
But you can always just stop. I’m not forcing you to look…
I figured it wasn’t Cyd…she has the LOOOOOOOOOOOONGEST legs I’ve ever seen. But then you all probably know that better than I do now
Yeah, Cyd Charisse was an obvious suspect. No luck with Leslie Caron either, although I’d say her legs were a very close match to those in the picture.
i stand by it , that they are those of Margaret Thatcher , from her days ( nights? ) as a coctail waitress , in Ronnie Scott’s club , London ?
she was quite a dazzler , back then ..
that , or Angela Rippon .
The Political Stance of the Cocktail Waitress explains much. 
I got quite attached to this one (sorry about the focus, that’s Victoria’s camerawork)
but one this size would fit better in my luggage.
btw, my guess would be Shirley McLaine, but she’s probably a bit too near the end of the era.
Just viewed 30 pages of Ginger Rodgers pix. No ID on the gams.
I am like IB in that I always assumed they were Betty Grable of the famous legs.
I will leave it up to you fellers to search out the actual owner of those gams. 
You beat me to that suggestion, but it’s not quite the same photo.
I’m still not 100% sure, once you’ve seen one pair of lady’s legs in fishnet stockings, they all get a bit samey.
Marlene Deitrich
You know…you could be right!!! I hadn’t thought of her…
Joe Namath.
I remember that!
