Lot 20 S1901 — S1910 — Solar System Space Stamps (set of ten covers) — /0/1/91

The USPS "Space Exploration" stamps, issued October 1, 1991, featured the nine planets and Earth's moon with their respective spacecraft, celebrating the solar system and kicking off National Stamp Collecting Month. The heavenly bodies shown are Mercury, Venus, Earth, (Earth's moon), Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

The USPS partnered with Paramount Studios to promote the stamps. The studio was celebrating the 25th anniversary of the Star Trek movies and television series. The stamp designs were unveiled on the bridge of the Starship Enterprise, the space vehicle featured in the series.

These stamps show some of the spacecraft and the images of the planets they captured as they flew by. Discoveries continue to be made with the space probes that still travel our solar system."

Each of my ten hand-painted first day covers depicts one of the nine planets plus the Earth's moon. Since Pluto had not yet had a fly-by or been explored by any manmade craft, I depicted the US.S. Enterprise from the show Star Trek.
