Why it was made: "Commemorative." They apparently stamped that decal on three different models of otherwise ordinary mainline matchbox cars. They paint matchbox cars at all to make them special; "I got a red one." "I'll trade you my blue corvette and my yellow and purple flames chevelle for your Halley's comet firebird."

Who would buy it: Collectors, because "commemorative." And apparently parents/loved ones of children, because it's a toy car. I take it you had fun playing with it as a kid? If so, I'd say it did its job. Those little comet decals seem to have helped form strong memories of it.

Eh, I get the sentiment. Nothing in space comes to a stop and most speeds are well beyond human comprehension. The Earth orbits at 67,000mph, escape velocity is like 27,000mph, the ground at the equator moves at about 1,000mph, the Voyagers are in the 30k range, and the Park Solar probe peaks over 400,000mph. So to learn that a comet is a tangible aviation speed was neat to me, at least

Mark Chesnutt? Nice!
