I love these old Brookfields with the strong embossing and all those patent dates. This is the 55 Fulton St with the big #1 and the E.R. on the skirt. On the reverse side is Cauvets Pat on the crown and two skirt patent dates below. A nice clean insulator with a strong mold line. There is an open bubble at the base of the skirt to the left of the E.R. embossing.A real neat old insulator. $30 shipped U.S. or Canada.
