Illustrated Guide to the Stamps of the World

The third installment of the Tiny Showcase Learning Press Illustrated Guide Series became available tonight. Gavin Potenza's Illustrated Guide to the Stamps of the World is now available for sale online.
Here's what the artist has to say about it: "These stamps were inspired by various elements surrounding the culture of the countries, including the Swiss-born color theorist Johannes Itten, old French Tarot cards, the Brazilian boardwalk Copacabana, German designer Otl Aicher, Mayan patterns, the Swiss Alps, sweater patterns, and op artist Victor Vasarely."
