Please help me identify these chairs...

They're from the mid-1960's.
Fiberglass, with vinyl seats.
I believe they're by Burke, and are possibly
Eames Burke Tulip Chairs? Or from Saarinen?

The legs look different from the chairs on
Star Trek Enterprise. The original seats are pink,
currently covered by blue cotton covers.

If anyone's familiar with this style, I'd
appreciate an idea of these chairs' value.

Thanks so much!
