One of my favourites is the early '90s trailer for the widescreen collection on VHS: http://youtu.be/mWxb3rmsp_w
I have it on the Die Hard widescreen VHS, but 1) it's a strange field-blended conversion (i.e. PAL format but does not have PAL speedup) and 2) the tape's pretty worn out and has loads of dropouts.
I also have the 2006 individual DVDs trailer as a MOV file, not sure where it came from but it has a Hyperspace watermark.
Edit: This one: http://youtu.be/1Q5kgNqryHY
The MOV is only 15fps and has heavily compressed audio, so quality is about the same as this Youtube version.
