Get America’s Smallest and Largest Stamps
America’s smallest stamp was an experiment to lower production costs and increase output. Measuring just .54" x .66", customers said it was too small and easily lost.
The largest US stamp measures 3" x 1.5" and shows the first image captured by the Mars Pathfinder. The stamp also has a USA-shaped perforation plus hidden words you can only see with a stamp decoder.
