I was just looking for Fedora materials suitable for an "Extreme IT Day" for high school and college students, and thought I'd share what I found. Some of these are oldies but goodies, and all of them are suitable for teens who may not have had prior exposure to free software.

Fedora Flyer by Max Spevack - (odt) (png-front) (png-back) (other languages)

Fedora Cheat Cube by Nushio - (png) (other languages)

The remainder are flyers from SXSW by Mo Duffy and the Design Team - the download links on that post are broken, so I tracked down the individual pdfs.
