This four-page flyer isn't particularly old (1990), but still exciting. The X-30 -- officially the X-30 National Aero-Space Plane (love that hyphen!) -- was a single-stage-to-orbit spacecraft (that is, it wouldn't have needed those great big booster rockets that seem sort of necessary).
According to Wikipedia, Reagan called for "...a new Orient Express that could, by the end of the next decade, take off from Dulles Airport, accelerate up to 25 times the speed of sound, attaining low-earth orbit or flying to Tokyo within two hours." It was going to be built by Rockwell.
It never got built. There's all sorts of history available on why, but it's safe to say that Mach 25 wasn't achievable, plus they decided to spend the $10 billion on homeless shelters and school lunch programs.
So, sadly, you can't fly to space in the X-30, but you can make a paper airplane that can attain low-living-room orbit and crash into the ficus in about two minutes. And that's almost as fun as popping up to the space station for some Tang and space sticks.
Here's an artist's conception of, I don't know, vapor trails in space or something. Below are the rest of the pages, including the never-cut-out, fold-and-glue-it-yourself glider kit.
UPDATE: Here's a full-size PDF of the glider page.
