This #10 envelope bore the image of GBW #314 on the front, and a
stylized route map on the back with an emphasis on the railroad's car ferry
connections at Kewaunee.
A couple of interesting points:
  - The envelope was addressed to "B.C.E. RR" -  the British Columbia
    Electric Railway, now doing business as the the Southern
    Railway of British Columbia.
 
  -  The envelope was postmarked January 18, 1971 and used the ubiquitous
    "White
    House & Flag" stamp of the era.
 
  - This combination of loco and system map also appeared on matchbooks
    from the era.
