Gorgeous 1930s or so ornate book chain with a dozen very ornately decorated brass four-hole ( 4 hole ) buttons that have been hung by jump rings to form perfect beads for this 16 inch long brass necklace. The buttons are about 10-11 mm in diameter.
Some darkened places here and there. Left to the new owner to decide if you wish to polish out. Straight out of a recent estate buy out and offered in 100% as found condition.
There was originally some bright plating but it's pretty heavily worn as it typical with this era of these necklaces.
