Stamps related to TRIX

In addition to photos, TRIX includes numerous images of postage stamps and other philatelic items. They provide extremely interesting background information of the topics covered and especially the historical persons behind these topics. Scott catalogue numbers appearing in the book are as given in the Scott Standard Postage Stamp Catalogue (Kloetzel, 2010).

Stamp collecting is a lifetime hobby of George. He is not the only one enjoying this hobby:

• Images of Mathematicians on Postage Stamps (Jeff Miller)
• Mathematical Stamp Collecting (Jim Kuzmanovich)
• Mathematics on Stamps (Hung Manh Bui)
