I collect postcards from the 1933-34 Century of Progress (COP) Worlds Fair, and have been working on a list of cards for the Fair. With a comprehensive list, I can know what I have, and also know what I still need. Many of the postcard sets that were created for the Fair have cards that are numbered consecutively, and I don't know the subjects for some of the numbers. If I knew the subjects, it would make it easier to search
ebay and other sources for the cards I need. So, I'm hoping some of you can help fill in some of my gaps.
Specifically, can anyone help me figure out what the subjects are for the numbers in the following series of COP postcards:
Gerson Brothers 341, 366
Illinois Photogravure 3, 5
Regensteiner CP-24
Western Photogravure 41-50, 54, 66, 68, 78, 79
