This beautiful cobalt blue pilgram hat style insulator commemorated the 100th anniversary of the Southern New England Telephone Co. The insulator was designed by SNET employee and telephone pioneer,, Roland Beeney and was produced by Imperial Glass. It was offered to SNET employees in 1976 but found more sales to the insulator collectors across America. There is a royal purple color listed, but the Telephone Pioneers commissioned just one color...cobalt blue. This piece is in excellent condition and price low at $25 plus actual shipping.
