On September 5, 1989, the Royal Mail of Great Britain issued a set of four stamps to commemorate Microscopy and the centennial of the Royal Microscopial Society. Shown here is a genuine First Day Cover, an envelope with the stamp, celebrating Modern Microscopy revolutionized by the invention of the scanning electron microscope in 1951 by Charles Oatley and Dennis McMullen, cancelled from the city of issue (Edinburgh) on the first day of issue captioned above. The stamp features a Microchip x 600. This technology paved the way for the most awesome development in microscopy to date - the scanning tunneling microscope, providing an unprecedented look at the atom.
The color cachet (artwork on the envelope) shows a drawing in silhouette of a person gazing into a modern microscope. The producer of this cover has also written a brief commentary about the advances in microscopy in the twentieth century.
Matted in blue, it's sized to fit a standard 8 x 10 frame. ***Certificate of Authenticity and Commentary Included***
