This is a series of commemorative insulators pictured with number one on the right front row and in numerical order left to right on each row going back. They are in mint condition. The first email saying I will take them for $1200+Postage gets them. It is not all that were produced for some had multiple colors in a year but there is at least one for each year shown. Contact me for more information if needed. See values on page 232 of the price guide. Priced well below book value.
