We've unstitched the blue Pandamonium mag from 1975 and then scanned it, so you can marvel at all the old advertisements and, er, the jokes. Some of the content from different times in 1975 is really not reproducible today and has been redacted. Other content would not be acceptable if published new today, but is included for historical relevance.
To hold the Rag Mag as it was originally created, print the complete sheets on white A4 paper double-sided, flipping on the short edge. It looks the best in colour. Align the centres, fold and staple, and then use a guillotine neatly to crop the edges. A long-arm stapler makes stapling much easier.
