I am trying to find some information on a piece of jewelry.
It appears to be a pendant that hooked into a lapel by a button
that is a silvery color, the pendant itself on the obverse side has a seated woman in a chair with 2 owls on either side of her
at her feet on the left is some books and on the right an oil lamp.
An eagle sits at the very top of the pendant, under the eagle the words "New York Public Library".
Under the figures feet are what appears to be stairs and written on the stairs are the words "Astor Lenox and Tilden Foundations"
then beneath that appears to be a windmill.
On the reverse side are the words "Opening of New Building May 23rd 1911"
Beneath that at the bottom are " Black, Starr & Frost
Thanks for any insight someone can give to me on this piece, there is nothing online that I could find to help me
