Large 11x22" advertising piece for the November 3-5, 1921 Omaha Aero Congress. Folded laterally three-times, photo collage top half followed by an extensive description of Omaha aviation interest and the various events. Would frame nicely. About fair because of frail folds and edge bumps. This is the only one of these I have encountered. (Note: because of scanner limitations, the bottom 20% is not shown)
