On occasion, the illustrated example of an animal depicted in philately is indistinct. Checking with the designer to understand what model they used is the only way to identify the animal. Here, the ammonite depicted is somewhat nebulous as text within the design also detracts from identifying it. In this instance, the designer used a fossil Parapuzosia seppenradensis as his model.
The registration receipt includes a pictorial hand cancel (#1) from Gosau-Hintertal, Austria. The hand cancel, dated 8/21/1983, was used at a stamp show in the city which included a special wandering tour of the area. Few registered letters are sent from such shows as they cost more to make when a collector can obtain an example of the cancel on a standard envelope or card.
