Great news! I'm going to be on STS-134, NASA's final Space Shuttle mission! Well, at least my face is, and you can send yours too. Choose between STS-133 (Discovery) or Endeavour's historic flight, and the cost is free. Simply go here and upload, crop and submit. For some reason, you must be at least thirteen years old.
Face in Space | Wired Science piece
Face in Space follows a long tradition of spacecraft carrying personal touches out of Earth’s gravity well. Since 1997, shuttle missions have carried elementary school students’ signatures as part of an outreach project called Student Signatures in Space. The Cassini spacecraft brought a disk of signatures into orbit around Saturn. The Phoenix Mars Lander took a DVD to Mars’ north pole. The Lunar Reconnaissance Orbiter took a microchip to the moon. And the exoplanet-hunting Kepler telescope took a DVD full of names and messages to ET into orbit.
The Voyager I spacecraft’s cargo was even more intimate: It carried a phonograph record containing recordings of a kiss, a mother’s first words to her child and Carl Sagan’s wife Ann Druyan’s brainwaves, among other Earthly sounds.

Printed out very small in a spiral-bound notebook? Doesn't seem likely.
All stuck onto a data DVD? Seems more likely, but rather abstract. Technically, yes, your face went into space as a collection of 1s and 0s, but unless they had one of the PCs on the ISS running them as a screensaver or something, unless your face could actually have been visible to someone up there (even if they were busy doing other things), if it wasn't ever displayed in space, it's kind of a tree-falling-in-the-forest-does-it-make-a-sound-if-mobody's-around debate on whether your face was in space.
