In 1950, as part of promoting a new exhibit on space exploration, the Hayden Planetarium in New York City put out the word that it was accepting applications from would-be space tourists. Over the next few years, hundreds of letters poured in. This is one of them, written by a man who would like to get to Mars early in order to corner the hot dog market there.
You can view several other letters at the American Museum of Natural History's website. They're equally delightful and packed with awesome Happy Mutant goodness—from a man who helpfully offered the planetarium his own, home-brew rocket schematics; to a man with the nickname "Stardust" who told the planetarium they could cancel his reservation if he was able to hitch a ride on a flying saucer sooner; to Barbara, a 16-year-old who informed the Planetarium that she "won't be content" until she was on a rocket headed to far-off space. Beautiful!
