Great, free vintage footage

If you are looking for unusual, historical or classical video footage, the Internet Archive is the place to go. You can download almost anything there, from old news items dating as far back as early last century, to entire movies from Hitchcock (his first 'talkie'!), to personal footage and concert registrations! There's some great stuff to be found. You name it, it's there. They offer download in various formats, amongst which Ogg, MPEG2 and MPEG4.
Many of the copyright falls under the 'Public Domain', which means that "the Work may be freely reproduced, distributed, transmitted, used, modified, built upon, or otherwise exploited by anyone for any purpose, commercial or non-commercial, and in any way, including by methods that have not yet been invented or conceived."

This is a veritable treasure chest of film and videomaterial! Here is a great one I found from the Prelinger Archive: As Boys Grow: Sex Education for Young Males, made in 1957.  A classic...
