I forgot to add that in most cases when an Ad Agency sent over a Quark Express or Pagemaker file on 44mb Syquest (remember those?) with some comps that had FPOs marked up on them, we'd normally get either slides or 4x5 transparencies with the job that we'd scan and crop EXACTLY like the FPO marked. So FPO also meant to the prepress guy "scan at hi res, place file in page layout program, and crop exactly like the art director has it marked on the FPO. Sigh, the "GOD". (Good Ole' Days) LOL!
