Four distinct themes matched to the days of the shows - these covers commemorate Nature (with the Nebraska statehood Forever stamp), Technology (with the Transcontinental Railroad Forever stamp), Culture and the ATA's 70th anniversary (with the Celebrate Forever stamp) and the Military (with one of the four Military Working Dog Forever stamps).
Each postmark corresponds to the theme of the show day and Military Working Dogs correspond to the stamps' first day of issue.
All four covers are included in this item and the price includes domestic postage. Exact positioning and density of cancellation may vary. The exact stamp for Military Working Dogs varies by set.
