The Ashfall Fossil Beds State Historical Park in cooperation with the Royal, Nebraska Post Office provided a special pictorial cancellation in conjunction with the US prehistoric mammal stamps issued on June 8th, 1996.

The four 32-cent postage stamps feature a mammoth, mastodon, the dawn-horse Eohippus, and the saber-tooth cat Smilodon. The souvenir envelope features a picture of a group of Ashfall horses (Pliohippus). The pictorial cancellation was used only on June 28-29, and only at Ashfall...after that the cancellation stamp was destroyed. These are not first day covers, but should be pretty collectable anyway! Stamps and special souvenir envelopes were offered in advance by mail order request and at the park on the two cancellation days. The souvenir envelope and pictorial cancellation sold for $2.00 with one stamp; $3.00 for the same with a block of all four stamps.

If you missed these special Ashfall covers and want one for your collection, the Shop has a couple of them available for trade only.
