Help with cameo necklace identification

Have been hanging on to this piece for a while and forget about it, stumble upon it, research it again - still turning up with nada! Are my jewelry experts in here able to assist with identifying this piece? Haven't tried to clean, but as you can see it needs some TLC.

Any help/guidance is always the utmost appreciated!!

The cameos appear to be a molded plastic but close-up photos will help.
I'm going to guess mid-20th century but look forward to seeing what the joolies say!

 

I'll take some more and post this evening!

 

@jezzra, when posting photographs, you will want to use Full Image rather than Thumbnail. That will make them easier for everyone to see. (Here's an example.) And, not to worry. All new members do the exact same thing in their first few posts.

I'd say early 1950s, costume. The molded lady is a classic costume design and she goes back to that era. She's not bakelite and I don't think celluloid, so that puts the best odds on post-WWII. The chain they used says late 40s to mid-50s to me too, but I defer to legit experts.
