Stamps from Mathematica

In Heinz Klaus Strick's biographies (see THIS LINK) he usually has a postage stamp as a portrait for the subject. In the case where there is no suitable stamp he has designed a stamp from the (fictional) country of Mathematica. These stamps are shown below.
The drawings are by Andreas Strick.
