Well, I've finally got around to it, and have scanned it in and pieced it together.
The full-size image is over 12Meg - so a big download - but it seems the only way to make faces identifiable.
I think it's around 1995, based on one face I could identify...anyone able to confirm this?
(click on image for the 12Meg huge version!)

If there's demand, I plan to scan in the others from the CHA Room and get them all on the CHA website - if you'd be interested in this, do let me know - otherwise I doubt I'll bother!
Cheers,
J
