On May 4, 2005, the USPS issued a set of four stamps honoring four American Scientists - John von Neumann, Josiah Willard Gibbs, Barbara McClintock, and Richard Feynman. Shown here is a genuine First Day Cover, an envelope with the stamp for John von Neumann cancelled from the city of issue (New Haven, CT) on the first day of issue captioned above. Note the special 'atom' postmark created to cancel this set of stamps on their 'birthday', featuring the name of each scientist.
The full-color cachet (artwork on the envelope) depicts a portrait of von Neumann, contributor to so many areas of mathematics, as well as being a pioneer of the modern digital computer. The cachet is printed on silk, the luster lending an-almost three-dimensional quality to the portrait. Collectible, historic, this cover honors one of the twentieth century's most influencial mathematicians...a member of the Manhattan Project, as well as the creator of game theory and the concept of cellular automata....John von Neumann.
Double matted in blue and white, it's sized to fit a standard 8x10 frame. ***Certificate of Authenticity Included***
