A great looking insulator that has the embossed Prism trade mark on one side of the umbrella and PATENTED JUNE 17 1890 on the other side. The color is a nice shade of blue. There are a couple of small open bubbles along the base, and a tick right on the top of the embossed N. I know you will love this piece. I have priced it at the low end of the price guides suggested value. Asking $125.00 plus actual shipping cost. Check, money order or PayPal, non fee.
