Antique BROOKFIELD glass insulator in classic aqua blue, dating to the late 1800s. This example is embossed “BROOKFIELD” only and does NOT include “New York”, which is typically associated with earlier or transitional production runs before Brookfield standardized city embossing.

These earlier Brookfield insulators are popular with collectors for their historical significance and mold variations.
