These attractive framed stamps of Halley's Comet show the Comet orbiting the sun and planets, Edmund Halley as the Comet, the Giotto Space Probe and 'Maybe Twice in a Lifetime.' They were issued for The Appearance of Halley's Comet in 1986 and the next time it will be visible is about 2062 - remember to look out for it! These stamps make a great gift for a friend or relative called Haley.
