Site maps of days gone by

Remember the good old days, when a site map of an entire university website could fit on an A3 page?

This is from a leaflet I found entitled "A guide to YorkWeb - the University's site on the World Wide Web". I'm not sure exactly when it's from, but the other side includes instructions for connecting to Windows 3.1, so it's a fair few years old*.

* Although, we did only recently move to the cutting edge of Windows XP, so it might not be quite as old as it looks :)
