Interplanetary Stamps
from Fancyclopedia 2 ca. 1959
Two stamps were designed by Russell Swanson for the PhilCon II. One was marked "Luna Colony Postage; First Moon Rocket — 1965"; a $5 blue horizontal. The other was a $10 red vertical "Mars Postage; First Mars Expedition, 1974", and depicted "Preparing the Atmosphere Rocket". They were sold in sheets of 40 of either issue for 50ยข by the PhilCon II Committee for publicity and revenue.
