1966 Exner Duesenberg sales brochure

I just received a near mint condition sales brochure for the 1966 Exner Duesenberg. It is in the supplied white envelope with the Indianapolis address on the back and Duesenberg embossed on the front. I assume that this is fairly rare and am wondering the value. Being that my great grandfather worked for Duesenberg in Indianapolis in the 20s/30s I have always been fond of Duesenbergs. Thank you. Attached are some sample photos. There are obviously more pages as the brochure is complete.
