Chandelier by Paavo Tynell circa 1940-1960 American

We have recently moved into a home that has a ceiling fixture by Paavo Tynell. We appreciate his work, but are planning on changing the décor of the room and are looking for values and potential places to try to sell it.

This is some of the info we found online so far:

Ceiling Fixture by Paavo Tynell circa 1940-1960 American

Ceiling Fixture has six enameled metal cylindrical shades with perforations with frosted glass diffusers all supported by decorative tubular brass arms. Above the shades there is a classic Paavo Tynell floral detail in brass and enamel. Designed for Lightolier.

I have attached 2 pictures of the our actual chandelier and one better picture I found of it on the internet (it is the same but not ours).

Any information you could provide about the chandelier or its value or places to contact to sell it would be greatly appreciated.

Thank you for your time.
