      Who knows... but now I have the real thing! Paul Bateman,
      who created both of the famous stamps there (the other was
      "four colors suffice") sent me an original he created in
      1985 (plus his permission):


      The Mersenne was used from 1966 to 1976, then the four colors was
      implemented. Apparantly the original template was discarded
      by a non-academic employee when the campus switched to a new
      postage system.
