There isn’t a whole lot out there pertaining to the Dukes. I collect it and it is tough to find. The collection I have attached is a very comprehensive photo collection in the Duluth area. They may be able to help, but I wouldn’t get your hopes up. Most of the early programs for the Dukes are very basic with no photos and there are very few of those to be had.
