VINTAGE 80’s(or earlier) Clip-on Costume Earrings

Excellent vintage condition. My neighbor gave these to me in the 80’s, these might be from the 40’s, 50’s or 60’s, not really sure as she was born in the 1940’s and not sure when she got them. I never wore them, they have been sitting in my jewelry collection for many decades. Thought I would put them up for sale so someone with more of a taste for authentic vintage would love them. The front looks impeccable, the back shows some tarnishing, no rust and is fully functional and clips well.
